The MODIS-AUX data set is an intermediate product that contains a subset of ancillary MODIS radiance and cloud mask data that overlaps and surrounds each CloudSat cloud profiling radar (CPR) footprint. The MODIS-AUX footprint will be a 3-km (along-track) by 5-km (across-track) box of MODIS data centered on each CloudSat profile location. Input data are obtained from the 1B-CPR and AN-MODIS ... products, and the MODIS-AUX data are used as input to the 2B-GEOPROF, 2B-CLDCLASS, 2B-TAU, and 2B-FLXHR algorithms in the CloudSat data processing system.
