FIGURE 1.2 The NPOESS Preparatory Project and NPOESS program summary following the Nunn-McCurdy program review and revisions (status as of October 2006). The mid-morning satellite coverage will be provided by the European MetOp satellite series, with descoped NPOESS satellites covering the early morning and afternoon orbits. Instruments removed from the core NPOESS program plan can be integrated and flown if outside funding will support the remaining development costs, as well as the cost of the instrument and its support. The canceled CMIS sensor will be replaced by a sensor now known as MIS. Although its specifications are not yet known, MIS will by design be a less expensive instrument with less developmental risk.

held in June 2007 in Washington, D.C. (referred to in this report as the June 2007 workshop). The NRC report on that workshop (NRC, 2008) is reprinted in Appendix B. For convenience, the issues that were of particular concern to workshop participants are reprinted in Box 1.1.

INPUT FROM NASA AND NOAA

Among the key inputs to the NRC’s June 2007 workshop were presentations by NASA and NOAA officials, especially “Mitigation Approaches to Address Impacts of NPOESS Nunn-McCurdy Certification on Joint NASA-NOAA Climate Goals,”4 which was derived from a NASA-NOAA draft report, “Impacts of NPOESS Nunn-McCurdy Certification on Joint NASA-NOAA Climate Goals,” referred to below as the NASA-NOAA study.5 The authors of the NASA-NOAA draft report envisioned a multistep study process that would lead to a
