GEWEX SRB Integrated Product (Rel-4) Longwave 3-Hourly Monthly Average by UTC Fluxes

Published by NASA/LARC/SD/ASDC | National Aeronautics and Space Administration | Catalog Last Checked: August 04, 2026 at 11:14 PM | Dataset Last Updated: June 22, 2026
GEWEXSRB_Rel4-IP_Longwave_3hrlymonthly_utc is theGlobal Energy and Water Exchanges (GEWEX) Surface Radiation Budget (SRB) Integrated Product (Rel-4) Longwave 3-hourly Monthly Average (also known as diurnal average) by UTC 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. A status flag of filled cloud properties is 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. These data are averaged by UTC from 3-hourly values. Data collection for this product is complete.
