hdf file naming convention

vgpm.yyyyddd.hdf.gz

vgpm = net primary production (units of mg C / m**2 / day) based on the standard vgpm algorithm
yyyy = year
ddd= day of year of the start of each 8day file
hdf = file type
gz = compressed with gzip (uncompress with gunzip)

The hdf files have metadata contained within them, which can be examined, for example, with program "ncdump".

npp is based on the standard vgpm, using modis chl, sst4, and par as input; clouds have been filled in the input data using our own gap-filling software.

For citation, please reference the original vgpm paper by Behrenfeld and Falkowski, 1997a as well as the Ocean Productivity site for the data.
