Description: The BEFlux VAP directly compares data from the three Normal Incidence Perheliometers, shaded pyranometers, and shaded pyrgeometers at the SGP CF. Extensive analysis with several years of data has produced limits of typical ranges of agreement when these instruments are performing as expected. These limits are used to screen the data, and then the average is taken of the two that agree best, given that at least two instruments agree to within the established limits. This is done for the downwelling direct normal and diffuse shortwave, and the downwelling longwave. The total (global) downwelling shortwave is then the sum of the direct and diffuse components.
