MODIS/Aqua Cloud Mask and Spectral Test Results 5-Min L2 Swath 1km V2

The Aqua Moderate Resolution Imaging Spectroradiometer (MODIS) NASA Level-2 (L2) Cloud Mask is one of four continuity products designed to sustain the long-term records of both MODIS and Visible Infrared Imaging Radiometer Suite (VIIRS) heritages. CLDMSK_L2_MODIS_Aqua is the short-name for the Aqua MODIS version of the Cloud Mask continuity product derived from the MODIS-VIIRS cloud mask (MVCM) algorithm, which itself is based on the MODIS (MOD35) algorithm. MVCM describes a continuity algorithm that is central to both MODIS data (from Terra and Aqua missions) and VIIRS data (from SNPP and Joint Polar Satellite System missions). Implemented to consistently handle MODIS and VIIRS inputs, the Aqua MODIS version-2.0 (v2.0) collection products use MODIS 6.1 L1B as input. The nominal spatial resolution of the Aqua MODIS L2 Cloud Mask is 1 km at nadir. The v2.0 collection starts from July 4, 2002 (2002-185).
