“Unseen Heroes” Awards for the S-NPP CDP Reset Recovery Team

On December 6, the NOAA Joint Polar Satellite System (JPSS) Program Office announced that the “Unseen Heroes” award would go to the Central Data Processor (CDP) Reset Recovery Team. It was given “in recognition of efforts to restore the Suomi-National Polar-Orbiting Partnership (S-NPP) satellite instruments after a central data processor reset.” This was a major effort in collaboration between the JPSS SDR teams and OSPO to recover the SNPP satellite after the instrument entered “Sun-pointing mode,” leading all of the onboard JPSS instruments to go offline and require restarting and revalidation. The CISESS and Consortium Scientist awardees were:

Advanced Technology Microwave Sounder Radiance Data Products Calibration and Evaluation

ESSIC/CISESS Scientist Hu “Tiger” Yang has a new article on the Advanced Technology Microwave Sounder (ATMS) in press at IEEE Transactions on Geoscience and Remote Sensing. The Advanced Technology Microwave Sounder (ATMS) is a passive microwave radiometer for the current generation of polar-orbiting meteorological satellites operated by NOAA. The first two ATMS instruments are onboard the Suomi National Polar-orbiting Partnership (S-NPP) and NOAA-20 satellites. The article explains several critical changes in the ATMS operational calibration algorithm since March 2017. Details of the radiance-based ATMS on-orbit calibration are documented and results of pre-launch calibration error budget analysis and post-launch calibration accuracy evaluation are also presented.
