Decadal Survey Recommendation NASA’s Response (2009)a NASA Update (2011)b
• Measurements of ocean vector winds and all-weather sea-surface temperatures descoped from the NPOESS C1 launch should be restored to provide continuity until the CMIS replacement is operational on NPOESS C2 and higher-quality active scatterometer measurements (from XOVWM, described in Table ES.1) can be undertaken later in the next decade. (p. 5) NOAA, with NASA reimbursable support (and starting in FY2010, NASA co-funding) has engaged in detailed design studies and international negotiations with JAXA to provide a vector wind measurement capability (dual-frequency scatterometer) to fly on the JAXA GCOM-W2 mission, scheduled to launch Net 2015. NOAA, with communication with NASA, is working with JAXA to negotiate near-real-time provision by JAXA of microwave radiometer measurements from the AMSR-Follow-On instruments on GCOM-W1 (11/2011 to 3/2012 LRD) and GCOM-W2, to continue the availability to the United States of all-weather SST measurements such as those initiated by the AMSR-E instrument on Aqua. The same negotiations cover near-real-time access to the vector wind measurements from a NOAA-supplied Dual-Frequency Scatterometer instrument for GCOM-W2. (p. 3) NOAA, with NASA reimbursable support has engaged in detailed design studies and international negotiations with JAXA to provide a vector wind measurement capability (dual-frequency scatterometer) to fly on the JAXA GCOM-W2 mission, scheduled to launch NET 2015.

In January 2011, NOAA informed NASA that it would not be able to support continued studies or future implementation of a scatterometer, but that NOAA would welcome NASA provision of NRT data from a research-based instrument. NASA discussions are ongoing with OSTP and OMB.

NASA and NOAA collaborate in joint discussions with ISRO for access to, and refinements of, Oceansat-2 scatterometer and ocean color data. (p. 38)
• The limb sounding capability of the Ozone Monitoring and Profiling Suite (OMPS) on NPOESS should be restored. (p. 5) NOAA and NASA co-funded the restoration of limb-sounding capability to the OMPS instrument package on NPP, and this has been completed. Ozone profiling through limb-sounding capability for NPOESS remains an open issue for NOAA. (p. 3) NOAA and NASA co-funded the restoration of limb-sounding capability to the OMPS instrument package on NPP, and this has been completed. Ozone profiling through limb-sounding capability for JPSS remains an open issue for NOAA. (p. 39)
The committee also recommends that NOAA:

• Ensure the continuity of measurements of Earth’s radiation budget (ERB) and total solar irradiance (TSI) through the period when the NPOESS spacecraft will be in orbit by:

   
—Incorporating on the NPOESS Preparatory Project (NPP) spacecraft the existing “spare” CERES instrument, and, if possible, a TSI sensor. (p. 5) NOAA reimbursable funding has been used by NASA to refurbish, test, and integrate the CERES FM-5 spare unit onto NPP. This task was completed less than 18 months after the decision to proceed. A TSI capability is not needed on NPP, as the NASA Glory mission, now due to launch NLT 11/2010 carries a state-of-the-art Total Irradiance Monitor instrument, and the recent NASA ESD Senior Review extended the ongoing SORCE mission (ACRIMSAT was also conditionally extended). (p. 3) NOAA reimbursable funding has been used by NASA to refurbish, test, and integrate the CERES FM-5 spare unit onto NPP. This task was completed in less than 18 months after ATP. A TSI capability is not thought to be needed on NPP, as the NASA Glory Mission carried a state-of-the-art TIM instrument, and the 2009 NASA ESD Senior Review extended the ongoing SORCE mission (ACRIMSAT was also conditionally extended).
