Surface Radiation Budget

The NASA/GEWEX Surface Radiation Budget (SRB) Release 4-IP data sets contain global 3-hourly, daily, monthly/3-hourly, and monthly averages of surface and top-of atmosphere (TOA) longwave and shortwave radiative flux parameters on a 1°x1° grid. Model inputs of cloud amounts and other atmospheric state parameters are also available in the ancillary data set. The primary inputs to the models are visible and infrared radiances from International Satellite Cloud Climatology Project (ISCCP) pixel-level (HXS) data along with cloud and surface properties derived from those data. NOAA/NCEI also provides ancillary files with the HXS data, of which temperature and moisture profiles and total column ozone were inputs to the SRB models.

Release 4-IP products differ substantially from the previous SRB Release 3.0 arising from numerous improvements of the algorithms and input data sets. The Algorithm Theoretical Basis Document (ATBD) provided online details all changes applicable to Release 4-IP. Temporal coverage of Release 4-IP extends from mid-1983 through mid-2017 for global shortwave fluxes and 1988 through 2009 for global longwave fluxes. Additional land-only longwave coverage is available from mid-1983 through 1987 and ocean-only from 2010 through mid-2017. All fluxes are available in netCDF-4 format.
