CoastWatch Primary Productivity Project
The VIIRS NOAA-20 Primary Productivity product estimates net carbon fixation by phytoplankton in oceanic waters using the algorithm of Behrenfeld and P. G. Falkowski (1997). Data sources used as in the algorithm are chlorophyll a, SST and PAR values from VIIRS NOAA-20. The chlorophyll a, SST, and PAR data used as inputs to the algorithm are included in the dataset. Data are mapped to a NASA 4km Standard Mapped Image. The monthly data are means of the daily composites
