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.

Best regards,
