| Abstract: |
| CERES has fairly accurate observations for top-of-atmosphere (TOA) broadband radiative flux. For each field of view (FOV), the vertical profiles of flux have also been computed; inputs include MODIS clouds, MODIS and MATCH aerosols, and soundings from NWP. These matching observations and calculations, which span the globe for 5 years, are in a voluminous public archive. For a few score sites with quality ground-based data, we have compared calculations with observations at the surface, as well as TOA; these have been placed in easy-to-use subsets and are available on line at our "CAVE" web site (http://www-cave.larc.nasa.gov/cave); from the same URL, one can also run the radiative transfer codes; and download global, gridded ASCII files for surface albedo each month. This exercise with satellites, ground networks, and matched radiative transfer calculations provides a database that is useful for testing GCMs. We plan to use this resource to investigate the shortwave (SW) and longwave (LW) fluxes simulated by some of the IPCC models. Other are welcome to join us. |
