Abstract	The NASA/GEWEX Surface Radiation Budget (SRB) project at NASA Langley Research Center has recently produced a climatology spanning 21.5 years (July 1983 December 2004) of shortwave (SW) and longwave (LW) radiative flux products. SRB estimates surface and top-ofatmosphere (TOA) radiative flux quantities using satellite observations, re-analysis meteorology, and ozone as inputs to parameterized radiation models. In this paper, monthly averaged SRB flux products are compared with similar products available from the European Centre for MediumRange Weather Forecasts (ECMWF) 40-year data set (ERA-40), NCEP/NCAR Reanalysis (NCEP) and the Clouds and the Earth's Radiant Energy System (CERES) surface radiation budget average (SRBAVG) for the period from March 2000 through February 2003. Both surface and TOA fluxes are compared. Select meteorological inputs to the algorithms will also be discussed and related to the flux differences. Global and zonal maps of selected months illustrate the extent of differences that will be taken as an indication of how the uncertainty in the meteorological fields affects the resulting fluxes. Finally, the fluxes from SRB will be validated against high quality measurements taken from surface sites of the Baseline Surface Radiation Network (BSRN). These results will have implications regarding the uncertainties limiting the estimate of surface fluxes.
