G. Falkowski (1997) with chlorophyll a and Photosynthetically Available Radiation (PAR) values from VIIRS SNPP and Sea Surface Temperature (SST) values from NOAA's Gridded Super-collated product is inputs. The science quality 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. |
