This data set contains a high quality Environmental Data Record (EDR) of nighttime cloud optical and microphysical properties (NCOMP) from the Visible Infrared Imaging Radiometer Suite (VIIRS) instrument onboard the Suomi-NPP satellite and is produced by the NOAA Satellite and Information Service (NESDIS). The EDR contains Cloud Optical Depth (COD), Cloud effective Particle Size (CPS), and Liquid and Ice Water Path (LWP and IWP). Liquid and ice water path are calculated subsequently from COD and CPS. The NCOMP algorithm uses VIIRS bands M7, M15, and M16. The EDR provides global coverage daily at a spatial resolution of 750 meters at nadir. VIIRS NCOMP data distributed by the NESDIS Data Exploitation (NDE) system and obtained from the Comprehensive Large-Array Stewardship System (CLASS) are distributed as single 86-second granules in NetCDF-4 format with metadata attributes included.
