3 Participation in EP, GDWG, GRWG Points of contacts/meeting participants: – EP: James J. Butler (NASA GSFC)/Jack Xiong (NASA GSFC) – GRWG: Jack Xiong (NASA GSFC) or Dave Doelling (NASA/GSFC)/Pat Minnis (NASA LaRC), Amit Angal (SSAI), Aisheng Wu (SSAI), Jon Fulbright (SSAI), Gene Eplee (SAIC), Ben Wang (SSAI), and Lawrence Ong (SSAI) Main contribution to GRWG actions: – Participation in organization of (JX) and discussions held during the GSICS Lunar Calibration Workshop (Jack Xiong, Gene Eplee, Ben Wang, Jon Fulbright, and Lawrence Ong) – POC for MODIS Terra and Aqua and their use as GSICS reference instruments in the reflected solar wavelength region (Jack Xiong) – GSICS DCC Chair (Dave Doelling) – GSICS Visible/Near InfraRed (VIS/NIR) Sub-group Chair (Dave Doelling) – «ATBD for DCC Technique of Calibrating GEO Sensors with Aqua MODIS for GSICS» (Dave Doelling) – «ATBD for Ray Matching Technique of Calibrating GEO Sensors with Aqua MODIS for GSICS» (Dave Doelling) – Articles submitted to GSICS Quarterly (Jack Xiong and Dave Doelling) Note: members are in blue 3

4 Highlights of NASA calibration activities of interest to the EP -EOS instrument status MODIS Terra and Aqua –Terra: Dec. 18, 1999 – Present Aqua: May 04, 2002 – Present Instrument parameterPerformance status Instrument operationStable On-board calibratorsNormal Blackbody calibrationsStable and T controlled Solar diffuser degradationLarger at smaller λs Radiometric responsivityLargest changes in VIS and NIR Spectral performanceSmall changes in CW and BW MODIS C6 L1B data can be downloaded from: http://ladsweb.nascom.nasa.gov/ Through 2/28/15 4

5 Highlights of NASA calibration activities of interest to the EP AIRS -EOS instrument status - Sensor is in excellent health -All instrument engineering parameters trended vs time are flat or changing slowly -Cooler A suffered an SEU on March 22 2014 that tripped a flag and caused the compressor to stop and as a safety precaution Cooler B was commanded to stop its compressor as well. -Both coolers were restarted on March 25, 2014. -On March 28 2014, Cooler A stopped sending telemetry and stopped accepting commands (but the compressor is still working) The problem is believed to be the same software problem that appeared occasionally during pre-launch testing and during on-orbit checkout in 2002 We believe power cycling the cooler will restore normal cooler operation, but have decided to leave the cooler alone for now because the compressor continues to work and science data quality is unaffected AIRS and CrIS brightness temperatures at 900 cm -1 were compared at Dome C for two years of data (April 2012 through March 2014) -CrIS was about 300 mK warmer than AIRS, but the one-sigma uncertainties were 400 mK At the April 2015 AIRS science team meeting, L. Strow reported on a study of all CrIS/AIRS SNO’s in 2013—he sees CrIS warmer by 100 to 250 mK depending on scene temperature. - Recent AIRS/CrIS comparisons 5

6 Highlights of NASA calibration activities of interest to the EP -NASA Suomi NPP Science Team transitioning from data assessment to data production NASA’s data distribution system assessed suitability of SNPP operational data records for climate science NASA’s new data distribution system produces data products suitable for NASA Earth Science and applications (i.e. continues the EOS data record) Assessment example: AIRS/CrIS skin surface T comparison using AIRS Version 6.13 and AIRS-like Version 6.13 algorithms -New data system enables efficient Implementation of: algorithm improvements new and/or different algorithm approaches data reprocessing 6

7 Highlights of NASA calibration activities of interest to the EP - CLARREO Status Update Full mission remains in pre-phase A studies, launch no earlier than 2023 Work on 2 RS and 2 IR instrument calibration demonstration systems continues (CU-LASP/GSFC for RS, UW/LaRC for IR) International collaboration options with UK, Italy, India in study 26 journal papers published/in press in 2014 and 10 journal papers currently submitted/in review in 2014 105 total journal papers published to date CLARREO Pathfinder Mission included in the Presidents FY16 proposed budget to Congress - Launch 2019/2020 on ISS -Includes both RS and IR spectrometers -Depends on Congress passing an increase in NASA Earth Science in FY16: may or may not happen: Congressional arguments underway. CLARREO provides the opportunity to intercalibrate 30 to 40 instruments in GEO and LEO orbits 7

8 Other NASA Items The link to NASA Aqua instrument information on the GCC webpage is incorrect – For example, the link to the Aqua instrument guide from the instrument information kiosk should be http://aqua.nasa.gov/content/instrumentshttp://aqua.nasa.gov/content/instruments – Need to examine other links (Contact for this?) NASA JPL AIRS Project participation in GRWG – In response to old GSICS EP action EP-10.13 – AIRS project is enthusiastic about participating in GRWG – T. Pagano, the NASA JPL AIRS Project Manager, has agreed to participate Goal is to finish, deliver, and formally close the following 2 GSICS EP actions: – EP-14.16: NASA to develop a list of data that need to be produced during the pre-launch instrument characterization; this list shall be appended to the guidelines on best practice for pre-launch characterization. (before the end of CY2015) – EP-14.08: NASA to present a paper about maturity levels of instrument calibration in support of re-processing, taking MODIS as an example, at the next web meeting of the Executive Panel 8
