This Environmental Data Record (EDR) provides daytime cloud optical and microphysical properties (DCOMP) from the Visible Infrared Imaging Radiometer Suite (VIIRS) onboard Suomi-NPP, NOAA-20, and NOAA-21.The EDR includes Cloud Optical Depth (COD), Cloud effective Particle Size (CPS), and Liquid and Ice Water Path. COD and CPS are retrieved simultaneously from visible and near-infrared observations. COD data is primarily retrieved from the conservative scattering channel at about 0.6 micrometer. The absorption channel at 2.2 micrometer provides additional information on CPS and helps indirectly to estimate COD by adjusting the difference in the phase function due to particle size. Liquid and ice water path are calculated subsequently from COD and CPS. The EDR provides daily global coverage at a spatial resolution of 750 meters at nadir. VIIRS DCOMP data is distributed by the Comprehensive Large-Array Stewardship System (CLASS) as single 86-second granules in NetCDF-4 format with metadata attributes included.
