SRB Previously Released Data and Information

The Surface Radiation Budget (SRB) data sets listed on this page are previous releases.

The most recent SRB Data Sets containing updated meteorological inputs are ordered from the SRB Data Sets web page.

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.
