Standard Products

This page provides access to our ocean net primary production (NPP) Standard Products. At this time, Standard Products are based on the original description of the Vertically Generalized Production Model (VGPM) ( Behrenfeld & Falkowski 1997a), MODIS surface chlorophyll concentrations (Chlsat), MODIS 11-micron daytime sea surface temperature data (SST), and MODIS cloud-corrected incident daily photosynthetically active radiation (PAR). Euphotic depths are calculated from Chlsat following Morel and Berthon (1989). A description of the VGPM and model code can be found under the Custom Products page. VGPM estimates of NPP for the entire SeaWiFS chlorophyll record can also be found under the Custom Products page.

Monthly Net Primary Production: April , 2004

Online Standard Products are available in different time spans (monthly or 8day averages), different global grid sizes (1080x2160 or 2160x4320), and different formats (hdf or xyz) (xyz format files are space-delimited {longitude latitude variable} text files.)
