Satellite Imagery and CMC Data

[Chris Lander]

I have two question (keep in mind that I am still trying to learn this 
program):

1st Question
My office has been downloading satellite images in tiff format from 
http://goes.gsfc.nasa.gov/goeseast/.  I tried load these images into 
GEMPAK, however, I get the following error message (which repeats itself 
6 times):

/070213/1651[IM -3] Image file $SAT/ir/IR4_20070213_1645 not a supported 
format/

I therefore assumed that tiff images were not supported, so I converted 
the image to jpg and gif.  Neither of them worked either.  So...  my 
question is, what image type does GEMPAK support, and where can I 
download them from.

2nd Question

We are downloading 525 Canadian Regional hiRes grib files from cmc twice 
per day.  How do I get these grib files into a format that can be read 
by GEMPAK.  I will also be looking to convert GFS and NAM grib data in a 
gempak format later as well, but I don't want to get to far ahead of 
myself just yet :)

Thanks in advance
