Gail, I am not familiar with distribution of ASAR data in GeoTIFF format, but I would guess it is 16bit data and so you will need to apply some scaling to it for visualization purposes. You could start adding the line: PROCESSING "SCALING=AUTO" But you may later want to specifically control the scaling. Read up on scaling in the raster howto.
