hdf file naming convention

par.yyyyddd.hdf.gz

par = photosynthetically available radiation (units of Einstein / m**2 / day )
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".

For citation, please reference the Ocean Productivity site for the data.
