At one time (probably about the timeframe that I had talks about getting
the CIMSS products into the Unidata-Wisconsin datastream) I talked with
someone at SSEC (can't remember who) about the possibility of a North
Polar product like the Antarctic one.  Since the enthusiasm for the
Antarctic product has been so low in the Unidata community, I did not
feel that it was very important to pursue acquisition of a N. Polar
one (if it exists).  I will be corresponding with Russ Dengel about
CIMSS products in the next several days, so I will ask him if he
knows if such a beast is being created routinely.

Good thought.

>So, just thought I would check with you guys first.

On a separate topic, I spoke to Chad about your GRIB decoding problem
at the hockey game.  He had a number of questions that I couldn't answer
(i.e. you should have been there), and he wanted one or more files
that don't decode correctly.  Can I get some?

>Thanks.

Later...
