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

December 19, 2022

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:

CISESS Welcomes Summer Interns in 2022

September 7, 2022

This past summer, ESSIC’s Cooperative Institute for Satellite Earth System Studies (CISESS) welcomed 22 interns to assist in the research of 24 ESSIC/CISESS scientists. Of the interns, three were graduate students, 14 were undergraduates and five were high school students. Several of these students were returning interns from previous semesters.

Stormy skies spell trouble afoot for the citizens of College Park

ESSIC Scientist Explains the Science Behind College Park’s Severe Storm

July 19, 2022

On Tuesday, July 12, the College Park area was ravaged by three storm complexes fueled by the influx of hot and humid air and powered by strong high-altitude winds. The storms brought down countless trees and caused thousands of people to lose power. ESSIC scientist Will Miller provides some commentary on the storm’s trajectory and intensification.
