ABSTRACT:: During the past few years many methods have been proposed for estimating
         surface radiative fluxes (shortwave radiation, Photosynthetically Active
         Radiation - PAR) from satellite observations. We have developed algorithms for
         computing the shortwave radiative flux (shortwave irradiance) at the ocean
         surface from visible radiance observations and they have been found to be quite
         successful under most atmospheric and cloud conditions. For broken clouds,
         however, the simple plane parallel assumption for solving the radiative transfer
         equations may need to be corrected to account for cloud geometry. The
         estimation of PAR is simpler because the most commonly used satellite radiance
         measurements cover a similar region of the solar spectrum.

         We are in the process of producing global llSW and PAR as a contribution to the
         Sequoia 2000 project (to implement a distributed processing system designed
         for the needs of global change researchers). Results from our algorithms
         developed for Sequoia and preliminary global surface solar irradiance and PAR
         fields will be presented and discussed.
