From page 10... ... sensors that would provide crucial continuity to certain long-term climate records, as well as other sensors that would have provided new measurement capabilities, are not funded in the certified NPOESS program. Presidential Decision Directive/NSTC-2, "Convergence of U.S.-Polar-Orbiting Operation Environmental Satellite Systems" May 5, 1994. Read the entire page →
From page 11... ... The complexity associated with combining both the hyperspectral sounding and the coastal waters imagery components into a single instrument is frequently cited as the key factor affecting programmatic risk for GOES-R. In this report, the ad hoc Committee on a Strategy to Mitigate the Impact of Sensor Descopes and Demanifests on the NPOESS and GOES-R Spacecraft reviews these recent changes to the NPOESS and GOES-R program and, as requested by NASA and NOAA (see Appendix A) Read the entire page →
From page 12... ... 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," 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. The authors of the NASA-NOAA draft report envisioned a multistep study process that would lead to a Available at http://www7.nationalacademies.org/ssb/NPOESSWorkshop_Cramer_NRC_06_19_07_final.pdf and also reprinted in Appendix C of the June 2007 workshop report. A final version of the NASA-NOAA report has not been released; a widely cited December 11, 2006, draft was posted by Climate Science Watch at http://www.climatesciencewatch.org/file-uploads/NPOESS-OSTPdec-06.pdf.

From page 13... ... These information gaps did not detract from the committee's science-based prioritization of the climate research capabilities to be recovered from those lost as a result of NPOESS program restructuring; however, they obviously restricted the committee's analysis of mitigation strategies. ONGOING COMMUNITY CONCERN It is important to note that community concerns about the adequacy of NPOESS for climate research existed even before the 2006 program restructuring, as is evident, for example, in the NRC decadal survey on Earth science and applications from space (NRC, 2007) Read the entire page →
From page 14... ... As a result, some participants heavily favored dedicated altimetry and scatterometry missions to fill this need. Further, some participants noted the critical importance of hyperspectral sounder measurements to climate science, suggesting restoration of CrIS/ATMS to the early-morning NPOESS orbit as well as the earli est-possible flight of a geostationary hyperspectral sounder to further improve temporal resolution.

From page 15... ... Further, many participants noted that discussions at the workshop were focused on solving near-term climate measurement continuity issues, but that there would remain a longer-term problem of sustaining support for climate science. Issues noted included finding an appropriate balance between new and sustained climate observations and managing infusion of technology into long-term observational programs (including the challenges of doing so with a multi-spacecraft -- block-buy -- procurement) Read the entire page →
