The MODIS/Terra Clear Sky Radiance 8-Day Composite Daily L3 Global 25km Equal Area (MODCSR_8) product is created from composited MODCSR_D files. Nine clear-sky radiance and reflectance statistics (bands 1-7 and 17-36, see description of the MODCSR_G product for description of statistics) are produced for day and night separately, for every calendar day from the previous eight days (eight MODCSR_D files). There must be valid clear-sky data from at least four of the eight days in order to generate a MODCSR_8 output file. The statistics include observed minus calculated data from bands 20, 22-25, and 27-36 and numbers of land vs. water observations. The data is global in extent at 25-km resolution. MODCSR_8 files are in Hierarchical Data Format (HDF).
