| Popis: | 28th European Photovoltaic Solar Energy Conference and Exhibition; 4029-4032 Satellite based models to retrieve solar radiation have been in development over the past three decades. These models produce global horizontal irradiance (GHI) and direct normal irradiance (DNI) using models that follow either an empirical or physical approach. Although empirical methods have been used traditionally for computing surface radiation the advent of faster computing has made operational physical models viable. The Global Solar Insolation Project (GSIP) is an operational physical model from the National Oceanic and Atmospheric Admnistration (NOAA) that computes GHI using visible and infrared channel measurements from Geostationary Operational Environment Satellites (GOES). GSIP uses a two-stage scheme that first retrieves cloud properties, then uses those properties in a radiative transfer model to calculate surface radiation. The National Renewable Energy Laboratory (NREL), University of Wisconsin, and NOAA have collaborated to adapt GSIP to create a 4-km GHI and DNI product every 30 minutes. In this paper we present a short outline of the method, a comprehensive validation using high-quality ground-based solar data as well as results of ongoing improvements in the modeling. |
