SRB Data Sets |
The NASA/GEWEX Surface Radiation Budget (SRB) Release-3.0 data sets contains global 3-hourly, daily, monthly/3-hourly, and monthly averages of surface longwave and shortwave radiative parameters on a 1°x1° grid. Cloud amounts and other atmospheric state parameters, used as inputs to the models, are also included in the data sets. Primary inputs to the models include: visible and infrared radiances, and cloud and surface properties inferred from International Satellite Cloud Climatology Project (ISCCP) pixel-level (DX) data; temperature and moisture profiles from GEOS-4 reanalysis product obtained from the NASA Global Modeling and Assimilation Office (GMAO); and column ozone amounts constituted from Total Ozone Mapping Spectrometer (TOMS) and TIROS Operational Vertical Sounder (TOVS) archives, and Stratospheric Monitoring-group's Ozone Blended Analysis (SMOBA), an assimilation product from NOAA's Climate Prediction Center. These data sets are also reformatted for the use of renewable energy and agricultural communities and made available through the Surface meteorology and Solar Energy (SSE) website. SRB data sets are also available from Clouds and the Earth's Radiant Energy System (CERES) project and the Fast Longwave and SHortwave Radiative Fluxes (FLASHFlux) project. The latter project provides SRB data on a near real-time basis. Both projects make use of global observations from CERES and Moderate-resolution Imaging SpectroRadiometer (MODIS) instruments.
Release-3.0 products differ substantially from earlier SRB Releases (2.0 and 2.5) arising from numerous improvements of the algorithms and input data sets. Temporal coverage of Release-3.0 is also extended to June 2007; Release-2.5 ended in June 2005. On-line documentation provides information on all changes applicable to Release-3.0. Users are encouraged to consult on-line documentation prior to using these data sets.
