Global Maps, time series: data files (compressed with bzip2) and visualizations (PNG format)

For each month, the separate satellite images are merged, after correction of biases, via a simple average of 
   whichever valid satellite observations are present per given pixel, e.g.,
   PAR' = ( PAR_SeaWiFS + PAR_MODIS_A + PAR_MODIS_T ) / 3
File format: unformatted binary flat files on standard L3 grid (4320x2160).
   Sample code to read a file in IDL:
   NL   = 2160L
   NS   = 4320L
   dat = fltarr(NS,NL)
   Openr,1,file_name
   Readu,1, dat
   Close,1
