Hi Barry,

Please read; I have an update on support for the TDWR-formatted imagery
that Bob Rabin and Joleen want to use.

OK.

I understand.

Here is the update.

It turns out that the NEXRAD Level III server in McIDAS-X was missing the
definitions for several )previously unseen by me) products, one of which is
the one specified in the TR0 file you sent in a previous email.

I just added support for images with product code 180 (256 level base 
reflectivity
with 0.08x1 Nmi x Deg resolution), and tested the code change in Unidata 
McIDAS-X...
the product now correctly displays.  I will be adding support for the other
products (product codes 183 16 level base velocity and 187 long range 16 level 
base
reflectivity) as soon as I can.

I don't know if you can incorporate the changed code (two files affected: 
nexradir.cp
and nexrutil.c) in the SSEC v2015.1 release, but it will be ready by the MUG
meeting.

Cheers,

Tom
