Earth radiation budget
Broadband radiometer to cover the shortwave range 0.3-5.0 μm, the LW range 5-50 μm and the total range 0.3-100 μm. An additional channel, 0.7-5.0 μm, enables splitting the SW range. Details not yet available.
Follow-on of CERES flown in different configurations on TRMM, EOS-Terra, EOS-Aqua, SNPP and JPSS-1/NOAA-20; to replace RBI flown on JPSS-2.

Variable Relevance for measuring this variable Operational limitations Explanation
Upward short-wave irradiance at TOA 2 - very high Information on BRDF needed. SW and LW broadband channels, and supporting narrow-bandwidth channels for cloud detection
Upward long-wave irradiance at TOA 1 - primary No specific limitation. SW, LW and Total (SW+LW) broadband channels
