INSTALLATION INSTRUCTIONS To install the MOD09 DB package on a Linux system (32 or 64 bit), first download the tarfile from ftp://ftp.ssec.wisc.edu/pub/gumley/modis_db/modis_db_20071217.tar.gz Then make a directory for the package, and unpack the tarfile. For example: cd $HOME (or wherever you want to install it) wget ftp://ftp.ssec.wisc.edu/pub/gumley/modis_db/modis_db_20071217.tar.gz mkdir modis_db cd modis_db tar zxvf ../modis_db_20071217.tar.gz See 00README.txt for detailed instructions on how to proceed from there. But if you hate to read manuals, here's a small Terra MODIS test case: mkdir test cd test wget ftp://ftp.ssec.wisc.edu/pub/gumley/modis_db/t1.07255.1651.\*.hdf.gz gzip -vd *.hdf.gz To run the test case: export MODIS_DB_HOME=$HOME/modis_db (or wherever you installed it) . $MODIS_DB_HOME/scripts/modis_db_env.bash run_mod09.csh terra t1.07255.1651.1000m.hdf t1.07255.1651.500m.hdf \ t1.07255.1651.250m.hdf t1.07255.1651.geo.hdf 2007255 1651
