hdf file naming convention

carbon.yyyyddd.hdf.gz

carbon = carbon (units of mg / m**3 )
yyyy = year
ddd = day of year of the start of each monthly 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".

clouds have been filled in the input data using our own gap-filling software.
