What is SRB?

The NASA/GEWEX Surface Radiation Budget (SRB) project produces and archives global 3-hourly, daily, monthly/3-hourly, and monthly averages of surface and top-of-atmospheric (TOA) longwave and shortwave radiative parameters on a 1°x1° grid. Starting no later than July 1983 and extending to December 2007.
