Abstract
This paper examines two co-located satellite-derived data sets over the Atmospheric Radiation Measurement (ARM) Southern Great Plains (SGP) site in central Oklahoma. The data sets, one derived from the National Aeronautics and Space Administration (NASA)/Langley Surface Meteorology and Solar Energy (SSE) Data Base and the other from the State University of New York at Albany (SUNY/Albany) satellite-based model, are compared with each other as well as with a high-quality surface station located at the Central Facility (CF) of the ARM/SGP site. The purpose of the study is two-fold: (1) to benchmark the two satellite-derived data sets with each other and (2) to examine the spatial variability of the higher-resolution SUNY data within the NASA cell that overlays the ground station. The results show variations in seasonal biases between the two satellite-derived data sets and the ground station. In addition, the distribution of high-resolution values within a NASA grid cell varies from month to month possibly due to variations in cloud conditions and surface reflectance characteristics that occur across the seasons.
