CERES Data and Information

The Clouds and the Earth's Radiant Energy System (CERES) is a key component of the Earth Observing System (EOS) program. The CERES instruments provide radiometric measurements of the Earth's atmosphere from three broadband channels. The CERES missions are a follow-on to the successful Earth Radiation Budget Experiment (ERBE) mission. The first CERES instrument (PFM) was launched on November 27, 1997 as part of the Tropical Rainfall Measuring Mission (TRMM). Two CERES instruments (FM1 and FM2) were launched into polar orbit on board the EOS flagship Terra on December 18, 1999. Two additional CERES instruments (FM3 and FM4) were launched on board EOS Aqua on May 4, 2002. The latest CERES instrument (FM5) was launched on board the Suomi National Polar-orbiting Partnership (NPP) satellite on October 28, 2011.

 

The newest instrument (FM6) is one of five that launched Nov. 18, 2017 on the National Oceanic and Atmospheric Administration's (NOAA) Joint Polar Satellite System 1 (JPSS-1), which opened its covers on Jan. 05, 2018. The release of instrument and ERBElike data from FM6 is scheduled for June 2018. CERES FM6 First Light Imagery

Spatially (1°x1° lat/lon regional, 1° zonal, global) and temporally (monthly, climatological, etc.) averaged fluxes where the TOA net flux has been energy balanced.

EBAF

Energy Balanced and Filled (EBAF)​
- TOA: CERES TOA all-sky and spatially complete clear-sky fluxes, where TOA net flux is constrained to ocean heat storage.
- Surface: Computed surface clear-sky and all-sky fluxes consistent with the EBAF-TOA fluxes.
