Top-of-the-atmosphere reflected shortwave radiative fluxes from GOES-R

Abstract. Under the GOES-R activity, new algorithms are being developed at National Oceanic and Atmospheric Administration (NOAA)/Center for Satellite Applications Research (STAR) to derive surface top-of-the-atmosphere (TOA) shortwave (SW) radiative fluxes from Advanced Baseline Imager (ABI), primary instrument on GOES-R. This paper describes a support effort in development evaluation of ABI capabilities such fluxes. Specifically, scene-dependent narrow-to-broadband (NTB) transformations facilitate use observations TOA. Simulations NTB have been performed with MODTRAN 4.3 using an updated selection atmospheric profiles implemented final specifications. These combined angular distribution models (ADMs), which synergy ADMs Clouds Earth's Radiant Energy System (CERES) simulations. Surface conditions scale products as needed compute TOA come International Geosphere–Biosphere Programme (IGBP). Land classifications 1/6? resolution 18 types converted 2 km grid over contiguous United States (CONUS) subsequently re-grouped 12 IGBP match classification CERES ADMs. In simulations, default information aerosols clouds is based that used MODTRAN. Comparison derived made those CERES, level agreement both clear cloudy documented. Possible reasons differences discussed.
