GEWEX SRB Integrated Product (Rel-4) Longwave 3-Hourly Fluxes

Published by NASA/LARC/SD/ASDC | National Aeronautics and Space Administration | Catalog Last Checked: May 06, 2026 at 06:39 PM | Dataset Last Updated: April 20, 2026
GEWEXSRB_Rel4-IP_Longwave_3hrly is the Global Energy and Water Exchanges (GEWEX) Surface Radiation Budget (SRB) Integrated Product (Rel-4) Longwave 3-hourly data product. It contains global fields of 26 longwave surface, Top of Atmosphere (TOA), and atmospheric profile radiative parameters derived with the Longwave algorithm of the NASA World Climate Research Programme/Global Energy and Water-Cycle Experiment (WCRP/GEWEX) Surface Radiation Budget (SRB) Project. This version is known as Release 4-Integrated Product. The fluxes include all-sky, clear-sky and pristine-sky TOA upward fluxes (outgoing longwave radiation, OLR), all-sky, clear-sky and pristine-sky upward and downward fluxes at: tropopause, 200hPa, 500hPa and surface. In addition to the fluxes a day/night flag and a status flag of filled cloud properties are also included. Inputs to the longwave algorithm are cloud information based on ISCCP HXS, meteorology from ISCCP nnHIRS, SeaFlux SST and surface, LandFlux meteorology, and MERRA-2 conditionally. The temporal range is January 1988 through December 2009, with the ends bound by input constraints. Data collection for this product is complete.
