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.)
