Disclaimer: This dataset was superceded by an improved reprocessed product. Please see the documentation tab below for links to the reprocessed dataset. This dataset contains an operational Environmental Data Record (EDR) of Ocean Color/Chlorophyll (OCC) from the Visible Infrared Imaging Radiometer Suite (VIIRS) instrument onboard the Suomi-NPP satellite and is produced by the NOAA Environmental Satellite, Data, and Information Service (NESDIS). The OCC EDR provides chlorophyll-a (Chl-a) concentration, Normalized Water-Leaving Radiance (nLw), Inherent Optical Properties of Absorption (IOP-a), Inherent Optical Properties of Scattering (IOP-s), Diffuse Attenuation Coefficient for the down-welling spectral irradiance (Kd490), and Diffuse Attenuation Coefficient for the down-welling photo-synthetically available radiation (KdPAR) at a spatial resolution of 750 meters at nadir. The Ocean Color/Chlorophyll retrieval algorithm utilizes the VIIRS spectral bands M1-M7 (410 nm-862 nm) and M8 (1.24 micron), M10 (1.61 micron), and M11 (2.25 micron). By default, IDPS VIIRS OCC data obtained from the Comprehensive Large-Array Stewardship System (CLASS) are distributed in four aggregated 86-second granules in Hierarchical Data Format v.5 (HDF5) with metadata attributes included.
