CERES Edition 4B SYN Product Release Announcement

[ASDC - micook]

These products contain gridded, regionally averaged data of CERES-observed and geostationary imager-derived reflected shortwave (SW), emitted longwave (LW) and top-of-atmosphere (TOA) fluxes. In addition, they contain computed SW and LW surface, TOA, and in-atmosphere fluxes. They also include cloud properties derived from either MODIS or VIIRS, as well as from geostationary satellite imagers. They include aerosol optical thickness derived from MODIS or VIIRS imagers and an aerosol transport model, and they include meteorological information from reanalysis data products. The products additionally include the following computed information: direct and diffuse fluxes at the surface, UV fluxes and index, Photosynthetically Active Radiation (PAR) fluxes, and entropy produced by radiative heating and cooling.
The hourly product resolves diurnal cycles.

The data are available at three temporal scales:
• Hourly: CER_SYN1deg-1Hour_Terra-Aqua-NOAA20_Edition4B
• Daily: CER_SYN1deg-Day_Terra-Aqua-NOAA20_Edition4B
• Monthly:
o Averaged 24 hours per month: CER_SYN1deg-MHour_Terra_Aqua_NOAA20_Edition4B
o Average of all daily values per month: CER_SYN1deg-Month_Terra_Aqua_NOAA20_Edition4B
These products are available from March 2000 to June 2025, with more data becoming available as forward-processing continues.
These data products are also available from the ASDC via the following options:
