Thanks.  GEMPAK doesn't have decompress built in so we would have to at
least
decompress and keep about 12 hours or so on disk uncompressed.

Robert...

I can't give you specifics on hardware, as I'm not sure what it is except
I know that it is a two cpu Intel system running Linux.  I *think* it has
1gb of memory.  We have *LOTS* of disk space, as that is required for the
radars.

It looks like we're up to 125 CRAFT radars, checking over the last month,
though in recent days, we've been getting 123.

Here is the space usage for the first four days of the month.  This is the
actual modified bzip2 compressed data that comes across LDM.

May 1   21.8gb
May 2   17.4gb
May 3   14.0gb
May 4   13.4gb

We don't decompress the data, as it takes too much disk space.  Our
algorithms
have data decompression code built.  If you wish to decompress the data
before
writing to disk, your space needs will be 10x to 15x more than the above
numbers.
