SRB Data Sets |
The Surface Radiation Budget (SRB) data sets contain global 3-hourly, daily and monthly averages of surface longwave and shortwave radiative properties, cloud amount, and meteorology computed using models. The main input data for these models include cloud information, top-of-atmosphere radiances and profiles of atmospheric water vapor and temperature. Some of the input data include Earth Radiation Budget Energy (ERBE) top-of-atmosphere clear-sky albedo and International Satellite Cloud Climatology Project (ISCCP) radiances and cloud amount. SRB parameters derived for the renewable energy community are also available from the Surface meteorology and Solar Energy (SSE) data set. Other SRB data are available from Clouds and the Earth's Radiant Energy System (CERES) and Multi-angle Imaging SpectroRadiometer (MISR).
An important difference between the Release 2.5 data set and the corresponding Release 2.0 data set is the use of Goddard Earth Observing System model version 4 (GEOS-4) meteorological inputs for the Release 2.5 data set in place of GEOS-1 for Release 2.0 and Release 2.1. Temporal Coverage also differs with Release 2.1 ending in October 1995 while Release 2.5 extends through June 2005. Please refer to SRB Previously Released Data Sets if you need older versions of these data.
