Executive Summary • OSTP requested NOAA and NASA to provide: – An analysis of possible mitigation options of the climate impacts of the NPOESS Nunn-McCurdy Certification through 2026 – An assessment of the potential costs of these options • Primary goal: Ensure continuity of long-term climate records • NOAA and NASA analyzed the following options: – Remanifesting the climate sensors on NPOESS spacecraft – Placing sensors on currently planned non-NPOESS spacecraft – Developing new gap-filling climate satellite missions – Partnering opportunities • Key results: – Work in progress: still assessing options – Multiple options exist to mitigate the loss of sensors from NPOESS – Options consistent with Decadal Survey recommendations – Partnering for altimetry could provide significant cost savings June 19, 2007 2 Pre-Decisional Document: Assessment involves preliminary ROM cost estimates only PREPUBLICATION COPY -- SUBJECT TO FURTHER EDITORIAL CORRECTION 57

– Reduced Capability – Provides sea surface temperatures, sea ice and snow cover extents, soil moisture, ocean surface wind speed, water vapor, and precipitation rates even in the presence of heavy cloud cover – Continuous records date back to 1987 • Visible Infrared Imaging Radiometer Suite (VIIRS) – Reduced Coverage (Absent from 0930 Orbit)

Development of Mitigation Options • Multiple options exist to mitigate the loss of sensors from NPOESS • Developed options using following criteria: – Minimize risk to measurement continuity • First priority for existing climate data records – Minimize risk to existing programs – Cost effectiveness • Economies of scale • Leverage planned missions and sensors including partnerships with other space agencies June 19, 2007 5 Pre-Decisional Document: Assessment involves preliminary ROM cost estimates only PREPUBLICATION COPY -- SUBJECT TO FURTHER EDITORIAL CORRECTION 60

Potential Mitigation Options • Option 1: NPOESS + Gap Filler Climate Satellite • Option 2: Sequential Climate Satellites • Option 3: Sequential Climate Satellites w/ TSIS Redundancy • Option 4: Sequential Climate Satellites w/ TSIS Redundancy & Operational Risk Reduction • These options also include free-flyer altimetry missions and climate data record science support June 19, 2007 6 Pre-Decisional Document: Assessment involves preliminary ROM cost estimates only PREPUBLICATION COPY -- SUBJECT TO FURTHER EDITORIAL CORRECTION 61
