I know that's not the answer you were hoping for, but copyright issues make the situation more complicated than it appears. Best, Michael James Unidata Support > I use MTSAT/METEOSAT satellite data obtained as AREA files from > http://satepsanone.nesdis.noaa.gov, but am having trouble using such files > in GEMPAK.
