USAGE: mod29.pl dirinout tag listfile gpdfile
[chanlist [latlonlistfile [keep [rind]]]]
defaults: 1 none 0 50
dirinout: directory containing the input and output files.
tag: string used as a prefix to output files.
listfile: text file containing a list of MOD29 files to be gridded.
gpdfile: .gpd file that defines desired output grid.
chanlist: string specifying channel numbers to be gridded. The default
is 1, i.e. grid channel 1 only. The channel numbers are:
1: icer Sea Ice by Reflectance - 8-bit unsigned
2: irqa Sea Ice by Reflectance PixelQA - 8-bit unsigned
3: temp Ice Surface Temperature - 16-bit unsigned (kelvin * 100)
4: itqa Ice Surface Temperature PixelQA - 8-bit unsigned
5: icet Sea Ice by IST - 8-bit unsigned
6: icrt Combined Sea Ice - 8-bit unsigned
latlonlistfile: text file containing a list of MOD02 or MOD03 files whose
latitude and longitude data should be used in place of the latlon
data in the corresponding MOD29 files in listfile. The default is
\"none\" indicating that the latlon data in each MOD29 file
should be used without substitution.
keep: 0: delete intermediate chan, lat, lon, col, and row files (default).
1: do not delete intermediate chan, lat, lon, col, and row files.
rind: number of pixels to add around intermediate grid to eliminate
holes in final grid. Default is 50.\n\n";

NSIDC has determined that the browse images for this data set contain errors. The science granules are unaffected. We have removed the browse images until the data provider corrects the problem and resends new files. Although we are currently unable to estimate when the reprocessing will be complete, NSIDC will make the new images available as soon as they are delivered.
