forcing/climate research. Instruments include aerosol optical instrumentation, a CCN spectrometer, and in situ chemical analysis samplers.

Satellite Technology Development

  • Development of Extinction Profile Measurement Capability: The goal is to develop the capability to measure extinction profiles (vertically resolved aerosol optical depths) on a global scale from a satellite.


The following projects are necessary to assure that the preceding technical recommendations are integrated and coordinated across the program, and that the results of the research are communicated promptly and authoritatively to those requiring technical guidance for decisionmaking.

  • Coordination: The goal is to maintain communication among projects regarding the technical details of the ongoing efforts. Included are small projects for linking the research efforts, tracking projects, and reporting research results.

  • Integration and Assessment: This small project will organize the data on aerosol forcing generated by the United States into formats suitable for presentation to the Intergovernmental Panel on Climate Change and other scientific and administrative bodies with differing requirements.

  • Integration of U.S. Research on Aerosol Forcing of Climate: While some aspects of the U.S. research of aerosol forcing of climate will be supported directly by the funding agency members of ICARUS, there are others that may not be or that will require some additional coordination. Typically, these efforts include the maintenance of data quality assurance efforts, the construction of program-wide data bases, model and measurement intercomparison studies, and the support of meetings.
