NASA's Atmospheric Science Data Center (ASDC) has released the Edition2B Suomi National Polar-orbiting Partnership (Suomi NPP) Clouds and the Earth's Radiant Energy System (CERES) Single Scanner Footprint One Degree (SSF1deg) data product suite. These Level 3 gridded data products provide regional averages of CERES Top of Atmosphere (TOA) fluxes, aerosols, and clouds derived from the Visible-Infrared Imager-Radiometer Suite (VIIRS) instrument.
The SSF1deg product suite also incorporates meteorological information from the Modern-Era Retrospective analysis for Research and Applications, Version 2 (MERRA-2) data product (from the Global Modeling and Assimilation Office) to help researchers understand how clouds and aerosols change the amount of radiation reflected or emitted by the Earth.
The CERES project is a key component of the Earth Observing System (EOS) program, with a primary objective to make radiometric measurements (in broadband channels) of Earth's atmosphere to monitor the planet's radiation budget.
The CERES Flight Model 5 (FM-5) and the Visible-Infrared Imager-Radiometer Suite (VIIRS) instruments were launched onboard the Suomi NPP satellite on October 28, 2011.
