Cover: A digitally enhanced image created from data acquired by a Geostationary Operational Environmental Satellite (GOES) operated by NOAA and built by NASA; by NASA’s Sea-viewing Wide Field-of-view Sensor (SeaWiFS) satellite; and by Advanced Very High Resolution Radiometer (AVHRR) instruments carried aboard NOAA’s Polar Orbiting Environmental Satellites (POES). These data were draped across a digital elevation model of Earth’s topography from the U.S. Geological Survey. Heavy vegetation is shown as green and sparse vegetation as yellow. The heights of mountains and depths of valleys have been exaggerated so that vertical relief is visible. The presence of the Moon in this image is an artistic addition; the lunar image was collected by GOES in September 1994 and has been magnified to about twice its relative size. The prominent storm raging off the west coast of North America is Hurricane Linda (1997). This image was created by Reto Stockli with the help of Alan Nelson, under the leadership of Fritz Hasler. A detailed description of how the image was generated is available at http://rsd.gsfc.nasa.gov/rsd/bluemarble/bluemarble2000.html.

THE NATIONAL ACADEMIES

Advisers to the Nation on Science, Engineering, and Medicine


The National Academy of Sciences is a private, nonprofit, self-perpetuating society of distinguished scholars engaged in scientific and engineering research, dedicated to the furtherance of science and technology and to their use for the general welfare. Upon the authority of the charter granted to it by the Congress in 1863, the Academy has a mandate that requires it to advise the federal government on scientific and technical matters. Dr. Ralph J.Cicerone is president of the National Academy of Sciences.


The National Academy of Engineering was established in 1964, under the charter of the National Academy of Sciences, as a parallel organization of outstanding engineers. It is autonomous in its administration and in the selection of its members, sharing with the National Academy of Sciences the responsibility for advising the federal government. The National Academy of Engineering also sponsors engineering programs aimed at meeting national needs, encourages education and research, and recognizes the superior achievements of engineers. Dr. Charles M.Vest is president of the National Academy of Engineering.


The Institute of Medicine was established in 1970 by the National Academy of Sciences to secure the services of eminent members of appropriate professions in the examination of policy matters pertaining to the health of the public. The Institute acts under the responsibility given to the National Academy of Sciences by its congressional charter to be an adviser to the federal government and, upon its own initiative, to identify issues of medical care, research, and education. Dr. Harvey V.Fineberg is president of the Institute of Medicine.


The National Research Council was organized by the National Academy of Sciences in 1916 to associate the broad community of science and technology with the Academy’s purposes of furthering knowledge and advising the federal government. Functioning in accordance with general policies determined by the Academy, the Council has become the principal operating agency of both the National Academy of Sciences and the National Academy of Engineering in providing services to the government, the public, and the scientific and engineering communities. The Council is administered jointly by both Academies and the Institute of Medicine. Dr. Ralph J.Cicerone and Dr. Charles M.Vest are chair and vice chair, respectively, of the National Research Council.

Preface

Natural and human-induced changes in Earth’s interior, land surface, biosphere, atmosphere, and oceans affect all aspects of life. Understanding these changes and their implications requires a foundation of integrated observations—taken from land-, sea-, air-, and space-based platforms—on which to build credible information products, forecast models, and other tools for making informed decisions.

In 2004, the National Research Council (NRC) received requests from the National Aeronautics and Space Administration (NASA) Office of Earth Science, the National Oceanic and Atmospheric Administration (NOAA) National Environmental Satellite Data and Information Service (NESDIS), and the U.S. Geological Survey (USGS) Geography Division to conduct a decadal survey to generate consensus recommendations from the Earth and environmental science and applications communities regarding a systems approach to space-based and ancillary observations1 that encompasses the research programs of NASA; the related operational programs of NOAA; and associated programs such as Landsat, a joint initiative of USGS and NASA.

The National Research Council responded to this request by approving a study and appointing the Committee on Earth Science and Applications from Space: A Community Assessment and Strategy for the Future to conduct it. The committee oversaw and synthesized the work of seven thematically organized study panels.

In carrying out the study, participants endeavored to set a new agenda for Earth observations from space in which ensuring practical benefits for humankind plays a role equal to that of acquiring new knowledge about Earth. Those benefits range from information for short-term needs, such as weather forecasts and warnings for protection of life and property, to the longer-term scientific understanding necessary for future applications that will benefit society in ways still to be realized.

As detailed in the study statement of task (Appendix A), the NRC was asked to:

Unless stated otherwise, the term “space-based observations” of Earth refers to remote-sensing measurements enabled by instruments placed on robotic spacecraft.

  1. Review the status of the field to assess recent progress in resolving major scientific questions outlined in relevant prior NRC, NASA, and other relevant studies and in realizing desired predictive and applications capabilities via space-based Earth observations;

  2. Develop a consensus of the top-level scientific questions that should provide the focus for Earth and environmental observations in the period 2005–2015;

  3. Take into account the principal federal- and state-level users of these observations and identify opportunities for and challenges to the exploitation of the data generated by Earth observations from space;

  4. Recommend a prioritized list of measurements, and identify potential new space-based capabilities and supporting activities within NASA ESE [Earth Science Enterprise] and NOAA NESDIS to support national needs for research and monitoring of the dynamic Earth system during the decade 2005–2015; and

  5. Identify important directions that should influence planning for the decade beyond 2015.

As will be clear in reading this report, the committee devoted nearly all of its attention to items 2, 3, and 4. Challenged by the breadth of the Earth sciences, the committee was not able to provide a comprehensive response to item 1, although aspects of it are addressed implicitly, given that the status of the field and outstanding science questions informed the committee’s recommendations for new programs. The committee also did not address item 5 systematically, although many of the recommended programs extend beyond 2015 and therefore indicate directions for the decade 2015–2025.

At the request of agency sponsors and Congress, the committee prepared an interim report, Earth Science and Applications from Space: Urgent Needs and Opportunities to Serve the Nation.2 Published in April 2005, it described the national system of environmental satellites as “at risk of collapse” (p. 2). That judgment was based on the observed precipitous decline in funding for Earth observation missions and the consequent cancellation, descoping, and delay of a number of critical missions and instruments.3 A particular concern expressed in the interim report was maintaining the vitality of the field, which depends on a robust Explorer-class4 program and a vigorous research and analysis (R&A) program to attract and train scientists and engineers and to provide opportunities to exploit new technology and apply new theoretical understanding in the pursuit of discovery and high-priority societal applications.

Those concerns have greatly increased in the period since the interim report was issued, because NASA has canceled additional missions, and NOAA’s polar and geostationary satellite programs have suffered major declines in planned capability. In addition to a decision not to adapt the already completed Deep Space Climate Observatory (DSCOVR) for launch,5 NASA has canceled plans for the Hydros mission

In this report, “Earth science Explorer-class missions” refers to NASA’s Earth System Science Pathfinders (ESSP) and an even less costly new class of missions, which the committee refers to as the Venture class. According to NASA, the ESSP program “is characterized by relatively low to moderate cost, small to medium sized missions that are capable of being built, tested, and launched in a short time interval. These missions are capable of supporting a variety of scientific objectives related to Earth science, including the atmosphere, oceans, land surface, polar ice regions, and solid-Earth. Investigations include development and operation of remote sensing instruments and the conduct of investigations utilizing data from these instruments.” See “Earth System Science Pathfinder” at http://science.hq.nasa.gov/earth-sun/science/essp.html.

DSCOVR, formerly known as Triana, would have been the first Earth-observing mission to make measurements from the unique perspective of Lagrange-1 (L1), a neutral-gravity point between the Sun and Earth. DSCOVR would have a continuous view of the Sun-lit side of Earth at a distance of 1.5 million km. In addition to its Earth-observing instruments, DSCOVR was to carry an instrument that would continue the real-time measurements of solar wind that are currently being made by instruments on the Advanced Composition Explorer (ACE) spacecraft, which has been at L1 since October 1997. The solar-wind monitor was a high-priority recommendation of the 2002 NRC decadal survey in solar and space physics. See NRC, “Review of Scientific Aspects of the NASA Triana Mission: Letter Report,” National Academy Press, Washington, D.C., 2000, and NRC, The Sun to the Earthand Beyond: A Decadal Research Strategy in Solar and Space Physics, The National Academies Press, Washington, D.C., 2003.

intended to measure soil moisture, delayed the Global Precipitation Measurement (GPM) mission another 2.5 years,6 and made substantial cuts in its R&A program.7

Instruments planned for inclusion on the National Polar-orbiting Operational Environmental Satellite System (NPOESS)8 will play a critical role in maintaining and extending existing Earth measurements. In 2006, NPOESS underwent a recertification that resulted in a substantial diminution of its originally planned capabilities.9 In addition to a substantial increase in program costs (to at least $3.7 billion), delay of the first scheduled launch from 2010 to 2013, and reduction (from six to four) in the number of spacecraft that will be procured, the descoped NPOESS program provides only “core” sensors related to the primary mission of NPOESS, which is weather forecasting. “Secondary” sensors that would have provided measurements to ensure crucial continuity in some long-term climate records as well as other sensors that would have obtained new data are not funded by NOAA in the new NPOESS program.10

Plans to make the Landsat spacecraft operational by including a land-imaging sensor on NPOESS have also been abandoned. For more than 30 years, Landsat observations have provided the best means of examining the relationship between human activities and the terrestrial environment. Although NASA has plans to develop the Landsat Data Continuity Mission (LDCM), gaps in the Landsat record appear inevitable, and whether there will be an LDCM follow-on is unclear.

The sponsors of this study, the first NRC decadal survey in the Earth sciences, requested a report that would provide an integrated program of space-based and related programs that were ordered by priority, presented in an appropriate sequence for deployment, and selected to fit within an expected resource profile during the next decade.

Execution of the survey presented several challenges, chief among them that, prior to the inauguration of this decadal survey, the Earth science community had no tradition of coming together to build a consensus toward research priorities spanning conventional disciplinary boundaries. Geologists, oceanographers, atmospheric scientists, ecologists, hydrologists, and others rarely view themselves as part of a continuum of Earth scientists bound by common goals and complementary programs. It was the need to create a broad community perspective where none had existed before that was a particular challenge to this decadal survey. Furthermore, the breadth and diversity of interests of the Earth science communities required priority-setting among quite different scientific disciplines. That heterogeneity required a multidisciplinary set of committee and panel members (Appendix B); it also required involving the broad Earth science community from the start in defining the scope and objectives of the survey. The effort began by informing the community of the proposed study through an extensive outreach effort, including solicitation and evaluation of written comments on the proposed study. Several planning workshops were held, beginning with a major community-based workshop in August 2004 at Woods Hole, Massachusetts.

6

As the present report was being completed, survey members learned of possible changes in GPM funding that would result in even further delays. Indeed, GPM, which was assumed to be part of the approved baseline of programs on which the survey would build its recommendations, might, in fact, have to compete for funding with survey-recommended missions.

7

Total R&A for NASA science missions was cut by about 15 percent in the president’s 2007 budget (relative to 2005). In addition, the cuts were made retroactive to the start of the current fiscal year. Over the last 6 years, NASA R&A for the Earth sciences has declined in real dollars by some 30 percent.

8

Since the early 1960s, the United States has maintained two distinct polar weather and environmental monitoring satellite programs, one for military use and one for civilian use. Although data from both programs were exchanged, each program operated independently. In 1994, after a multiyear review concluded that civilian and military requirements could be satisfied by a single polar satellite program, President Bill Clinton directed the merger of the two programs into one—NPOESS. The program is managed by the triagency Integrated Program Office (IPO), using personnel of the Department of Commerce, Department of Defense, and NASA. See http://www.ipo.noaa.gov/.

The division of responsibilities between NASA and NOAA for Earth observations from space also required that the committee consider critical interagency issues. Historically, new Earth remote sensing capabilities have been developed in a process whereby NASA develops first-of-a-kind instruments that, once proved, are considered for continuation by NOAA. In particular, many measurements now being performed by instruments on NASA’s Earth Observing System of spacecraft—Terra, Aqua, and Aura11—are planned for continuation on the NOAA-Department of Defense next generation of polar-orbiting weather satellites, NPOESS. Problems in managing the transition of NASA-developed spacecraft and instruments to NOAA have been the subject of several NRC studies.12

A related issue concerns the process for extension of a NASA-developed Earth science mission that has accomplished its initial objectives or exceeded its design life. NASA decisions on extension of operations for astronomy, space science, and planetary exploration are based on an analysis of the incremental cost versus anticipated science benefits. Historically, NASA has viewed extended-phase operations for Earth science missions as operational and therefore the purview of NOAA. However, the compelling need for measurements in support of human health and safety and for documenting, forecasting, and mitigating changes on Earth creates a continuum between science and applications—illustrating again the need for multiple agencies to be intimately involved in the development of Earth science and applications from space.13

Previous NRC decadal survey committees in astronomy and astrophysics, planetary exploration, and solar and space physics were able to draw on NASA-sponsored community-generated roadmaps of highpriority near-term and longer-term missions and programs that would advance the field.14 In the absence of such roadmaps, the present survey began its work by soliciting concept proposals from the community. The committee issued a request for information (RFI) in early 2005 and received more than 100 thoughtful responses (the RFI is shown in Appendix D; responses are summarized in Appendix E). The responses were studied by members of the panels and helped to inform decisions regarding the recommended missions and associated programs.

Finally, participants in the survey were challenged by the rapidly changing budgetary environment of NASA and NOAA environmental satellite programs. By definition, decadal surveys are forward-looking documents that build on a stable foundation of existing and approved programs. In the present survey, the foundation eroded rapidly over the course of the study—in ways that could not have been anticipated. The recommended portfolio of activities in this survey tries to be responsive to those changes, but it was not possible to account fully for the consequences of major shocks that came very late in the study, especially the delay and descoping of the NPOESS program, whose consequences were not known even as this report went to press.15 Similarly, the committee could not fully digest the ramifications of changes

NASA did complete its Earth Science and Applications from Space Strategic Roadmap in 2005. However, that effort began after this decadal survey had been inaugurated, and the effort was truncated soon after the change in NASA administration in April 2005. Survey activities were well under way when the roadmap was completed in the middle of 2005.

For example, a key instrument on all six originally planned NPOESS spacecraft was the Conical Scanning Microwave Imager/Sounder (CMIS). CMIS was to collect global microwave radiometry and sounding data to produce microwave imagery and other meteorologic and oceanographic data. Data types included atmospheric temperature and moisture profiles, clouds, sea-surface winds, and all-weather land and water surfaces. CMIS contributed to 23 of the NPOESS environmental data records (EDRs) and was the primary instrument for nine EDRs. CMIS was terminated in the certified NPOESS program, and a smaller and less technically challenging instrument is planned as its replacement. The detailed specifications of the replacement have not been announced. Similarly, the mitigation plan for the altimeter, ALT, which was removed from the NPOESS C-3 and C-6 spacecraft, is also not known at this time.

in the GOES-R program of NOAA,16 and it was in no position to consider the implications of a possible large-scale reduction in funding and later delay of the GPM mission. GPM, a flagship mission of NASA’s Earth science program, was a central element in the baseline of programs that the decadal survey committee assumed to be in place when developing its recommendations.

Given the breadth of the Earth sciences, there were multiple ways to organize the present study. Organizers of the study considered a discipline-based structure focused on the atmosphere, ocean, land, cryosphere, and solid Earth. However, an important deficiency of that approach was its potential to deemphasize the interdisciplinary interactions of Earth as a system as they pertain to forcing, feedback, prediction, products, and services. After considerable discussion at the Woods Hole 2004 meeting, it was decided that the study would be organized with a committee overseeing the work of seven thematically organized study panels. The panels focused on

  1. Earth science applications and societal benefits;

  2. Land-use change, ecosystem dynamics, and biodiversity;

  3. Weather (including space weather17 and chemical weather18);

  4. Climate variability and change;

  5. Water resources and the global hydrologic cycle;

  6. Human health and security; and

  7. Solid-Earth hazards, resources, and dynamics.

Given that structure, disciplines such as oceanography and atmospheric chemistry, although not named in the title of a given panel, influenced the priorities of multiple panels. Oceanography, for example, was a key discipline represented in all the panels. Similarly, atmospheric chemistry was an important driver in the deliberations of several panels, including those on human health and security; land-use change, ecosystem dynamics, and biodiversity; climate variability and change; and weather. Moreover, NASA and NOAA have taken a similar interdisciplinary approach in their strategic planning; hence, this structure was thought to be of greater use for NASA’s and NOAA’s implementation plans. Nevertheless, there was concern in parts of the community that some sciences and applications might not be adequately addressed by the panel structure.

Each panel met three times during the course of the study. In several instances, panels also met jointly with other panels or with the committee. The committee met in whole or in part some 10 times during the study. Community outreach efforts included presentations and town hall sessions at professional meetings, including those of the American Geophysical Union and the American Meteorological Society; study updates posted to various newsletters; articles in professional journals; and the creation of a public Web

Plans to develop the next generation of operational sounder from geostationary orbit, the Hyperspectral Environmental Suite (HES), were terminated in late August 2006. HES, scheduled for launch in 2013, was a key sensor on the GOES-R series, NOAA’s next generation of geostationary environmental spacecraft. It was to provide high-spectral-resolution radiances for numerical-weather-prediction (NWP) applications and temperature and moisture soundings (and various derived parameters) for a host of applications dealing with near-term or short-term predictions. See, for example, Timothy J.Schmit, Jun Li, and James Gurka, “Introduction of the Hyperspectral Environmental Suite (HES) on GOES-R and Beyond,” presented at the International (A)TOVS Science Conference (ITSC-13) in Sainte Adele, Quebec, Canada, October 18-November 4, 2003, available at http://cimss.ssec.wisc.edu/itwg/itsc/itsc13/proceedings/session10/10_9_schmit.pdf#search=%22hes%20goes-r%22.

The term “space weather” refers to conditions on the Sun and in the solar wind, magnetosphere, ionosphere, and thermosphere that can influence the performance and reliability of space-borne and ground-based technological systems and that can affect human life and health.

18

There is no single definition of “chemical weather,” but the term refers to the state of the atmosphere as described by its chemical composition, particularly important variable trace constituents such as ozone, oxides of nitrogen, and carbon monoxide. Chemical weather has a direct impact in a number of areas of interest for this study, especially air quality and human health.

site. As noted above, members of the community were invited to submit ideas to advance Earth science and applications from space. Briefings were also given on many occasions to various NRC committees. Finally, numerous members of the community communicated directly with survey participants. Community input was particularly helpful in the final stages of the study to ensure that essential observational needs of disciplines would be met by the interdisciplinary mission concepts of the panels.

The final set of program priorities and other recommendations was established by consensus at a committee meeting at Irvine, California, in May 2006, and in later exchanges by telephone and e-mail. The committee’s final set of priorities and recommendations does not include all the recommendations made by the study panels, although it is consistent with them. As described in Chapter 2, the panels used a common template in establishing priority lists of proposed missions. Because execution of even a small portion of the missions on the panels’ lists was not considered affordable, the panels worked with committee members to develop synergistic mission “roll-ups” that would maximize science and application returns across the panels while keeping within a more affordable budget. Frequently, the recommended missions represented a compromise in an instrument or spacecraft characteristic (including orbit) between what two or more panels would have recommended individually without a budget constraint.

All the recommendations offered by the panels merit support—indeed, the panels’ short lists of recommendations were developed from the more than 100 RFI responses and other submissions—but the committee took as its charge the provision of a strategy for a strong, balanced national program in Earth science for the next decade that could be carried out with what are thought to be realistic resources. Difficult choices were inevitable, but the recommendations presented in this report reflect the committee’s best judgment, informed by the work of the panels and discussions with the scientific community, about which programs are most important for developing and sustaining the Earth science enterprise.

The process that resulted in the final set of recommendations and the usual procedures imposed by the NRC guard against the potential for anyone to affect report recommendations unduly. The vetting process for nominees to an NRC committee ensured that all survey members declared any conflicts of interest. The size and expertise of the committee served as a further check on individual biases or conflicts in that each member of the committee had an equal vote. The consensus-building process by which each panel produced short priority lists of missions and then a final set of roll-up missions ensured further vetting of the merits of each candidate mission by the entire committee. The committee, whose collective expertise spanned the relevant disciplines for this survey, then had the final say in reviewing and approving the overall survey recommendations.

On June 13, 2006, after a full House Committee on Science hearing on the recertification of NPOESS, Representative Sherwood Boehlert, chair of the House committee, sent a letter to Michael Griffin, administrator of NASA, requesting that the NRC decadal survey undertake additional tasks to “analyze the impact of the loss of the climate sensors, to prioritize the need for those lost sensors, and to review the best options for flying these sensors in the future.” NASA later sent the NRC a request to do the following:

  1. Analyze the impact of the changes to the NPOESS program, which were announced in June 2006…. The analysis should include discussions related to continuity of existing measurements and development of new research and operational capabilities.

  2. Develop a strategy to mitigate the impact of the changes described [in the item above]…. Included in this assessment will be an analysis of the capabilities of the portfolio of missions recommended in the decadal strategy to recover these capabilities, especially those related to research on Earth’s climate…. The committee should provide a preliminary assessment of the risks, benefits, and costs of placing—either on NPOESS or on other platforms—alternative sensors to those planned for NPOESS. Finally, the committee will consider the advantages and disadvantages of relying on capabilities that may be developed by our European and Japanese partners.

The present report provides a preliminary analysis of the first item (see, in particular, Chapter 9, “Climate Variability and Change”; also see Tables 2.4 and 2.5). Most of the tasks in the second item will be performed by a new panel appointed in early 2007 that will deliver a short report of a workshop in fall 2007 and a final report in 2008 (Tables 2.4 and 2.5 summarize the impact of NPOESS instrument cancellations and descopes).

Finally, the survey co-chairs and the study director wish to acknowledge the contributions to this report from Randy Friedl, a member of the Panel on Earth Science Applications and Societal Needs, who was unsparing of his time and offered wise counsel at several critical stages in the development of this report. He and his Jet Propulsion Laboratory colleague Stacey W.Boland provided invaluable assistance in synthesizing the work of the survey study panels, obtaining budget information, creating graphs, and critiquing large portions of Part I of this report.

ANTHONY HOLLINGSWORTH

It was with great sadness that the committee and the panels of the decadal survey learned of the death of Anthony Hollingsworth on July 29, 2007. Tony, a long-time scientist at the European Centre for Medium-Range Weather Forecasts, was a giant among his peers in numerical weather prediction and analysis, data assimilation, and the use of weather forecasts to meet broad societal needs. Tony was dedicated to the use of satellite observations of Earth to improve weather predictions for the benefit of society. He worked tirelessly in the scientific and political trenches of the world, always sharing his knowledge and valuable ideas with others in his gentle, unselfish way. He inspired people of all ages throughout his long and productive career, which still ended all too soon. He was a close friend of all who were fortunate enough to know him well.

Tony was one of the leaders of the decadal survey, arguing for the importance of diverse observations from satellites and other platforms to produce the most accurate and consistent analysis of the Earth system possible for initializing prediction models of the atmosphere, oceans, and land. He was the primary author of Appendix C, “Blending Earth Observations and Models—The Successful Paradigm of Weather Forecasting,” which tells the story of one of the greatest success stories of Earth science. Tony contributed greatly, as an individual and as a member of many international teams, to this success story. We will miss him greatly.

Natural and human-induced changes in Earth's interior, land surface, biosphere, atmosphere, and oceans affect all aspects of life. Understanding these changes requires a range of observations acquired from land-, sea-, air-, and space-based platforms. To assist NASA, NOAA, and USGS in developing these tools, the NRC was asked to carry out a "decadal strategy" survey of Earth science and applications from space that would develop the key scientific questions on which to focus Earth and environmental observations in the period 2005-2015 and beyond, and present a prioritized list of space programs, missions, and supporting activities to address these questions. This report presents a vision for the Earth science program; an analysis of the existing Earth Observing System and recommendations to help restore its capabilities; an assessment of and recommendations for new observations and missions for the next decade; an examination of and recommendations for effective application of those observations; and an analysis of how best to sustain that observation and applications system.
