    Metadata Updated: July 28, 2023

    THIS VERSION WAS DISCONTINUED on 2017-12-01. SEE THE NEW erdVH2018 DATASETS. Level-3 Standard Mapped Image (SMI), Global, 4km, Photosynthetically Available Radiation (PAR), Daily composite data from the Visible and Infrared Imager/Radiometer Suite (VIIRS), as processed by NASA GSFC Ocean Biology Processing Group (OBPG). VIIRS is a multi-disciplinary instrument that flies on the Suomi-NPP (National Polar-orbiting Partnership) satellite. Suomi-NPP is the initial spacecraft in the JPSS (Joint Polar Satellite Systems) series of spacecraft. JPSS is our Nation's next generation polar-orbiting operational environmental satellite system. JPSS is a collaborative program between NOAA and its acquisition agent NASA. VIIRS is the successor to MODIS for Earth science data product generation. (This version of the VH data was first released on 2016-04-01.)
