Hi Tom,

This can be done in McIDAS fairly simply.

OK.  You can create a local ADDE dataset of the images you have
downloaded.

This should be pretty easy.

OK.

McIDAS should work nicely.

> Perhaps you have a suggestion!

My suggestion is twofold:

1) upgrade your McIDAS installation to the latest Unidata release,
   v2007e

2) Do the conversion using McIDAS:

   - create an input ADDE dataset of the images in AREA format
   - create an output ADDE dataset of type NCDF for the converted images
   - use the McIDAS routine IMGCOPY do copy from the input dataset to
     the output dataset.  The conversion from AREA top netCDF will be
     done for you transparently

Things are going well, thanks!

As a contrast, we have had to start closing our windows at our
house up here in the Colorado foothills (elevation 8150') because
it is now getting quite cool to cold at night :-)

So, how best to proceed?

Since I am interested in seeing you get upgraded to the latest
McIDAS release (so the calibration coefficients for GOES-East/West
are up to date), I will offer to help you with the installation.
I can then setup the input and output datasets if you let me know
where the images to be converted can be found (this is a 2 minute
job).  Finally, I can give provide you with an example using
the mcrun'sh or mcbatch.sh scripts in the McIDAS distribution
to do the conversion.  My concept would be to make a copy of the
script (either one) and then modify the copy to include a looping
construct to work through all of the images in one go.

Please let me know how you would like to proceed.

Cheers,

Tom
