Welcome to the Custom Products path. Here you can access ocean net primary
production (NPP) data for alternative NPP algorithms and using either SeaWiFS, MODIS
or VIIRS data. You will also find visual comparisons of NPP algorithm products at
different temporal scales (e.g., annual, monthly), brief descriptions of each algorithm,
and code for your own algorithm implementation. To navigate the Custom Products
page, begin by selecting one of the top-level tabs located above (i.e., Online Data, Visual
Comparision, Model Description, Code).
To proceed directly to online data, simply click on one of the four NPP images
below. The first image will provide access to standard VGPM algorithm products, the
second gives NPP estimates from the Eppley-VGPM, the third gives access to NPP data
from the updated
(spectrally-resolved and depth-resolved) Carbon-based Production Model-2 (CbPM2).
Online products are provided at 8day and monthly time periods, and cover both (1080 x 2160) and (2160 x 4320) global grids in hdf format.
