DEPRECATED 2016-04-01 - SEE THE NEW erdVH2018 VERSION. Level-3 Standard Mapped Image (SMI), Global, 4km, Chlorophyll a, OCI Algorithm, Daily composite data from the Visible and Infrared Imager/Radiometer Suite (VIIRS). 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 in December 2014.)
