Abstract
The National Laboratory of the Rockies’ (NLR’) National Solar Radiation Database (NSRDB), sponsored by the U. S. Department of Energy (DOE) Solar Energy Technologies Office (SETO), is one of the most well-known solar resource datasets for the contiguous United States (CONUS). To provide continuous observation of solar radiation, the latest NSRDB utilizes high-resolution data from geostationary satellites positioned at Geostationary Operational Environmental Satellite-West (GOES-West) and GOES-East. The objective of this ongoing study is to specifically assess the impact of combining data from multiple satellites in the overlap regions of GOES-East and GOES-West. Our preliminary results indicate that the accuracy of the NSRDB is improved through a new blending algorithm that accounts for satellite viewing zenith angle and the scattering angle between the Sun and the satellite when selecting the appropriate satellite data to use at any location during different time of a day. As a result, the boundary seam present in the current NSRDB, resulting from a longitude-based selection, becomes effectively invisible when using this new algorithm.
