Re: nex2image and displaying output in NCEP N-AWIPS

Gregg,

The calibration bar units would be the only thing that the NCEP
distribution doesn't have. I can send you the 1km GINI radar files
from our LDM if that would be of use for you.

However, you may want to investigate the 1km products that NSSL
is working to produce (Ken Howard and Steve Vasiloff provided some
background to their QPESUMS product to us last year). I did modify
our GEMPAK distribution to read their NetCDF tiled files-
and hoping that they were going to produce single files rather than
tiles. The point here being that they are doing the 3-D volume level 2
radar data, and the AP/clutter removal). See the March 2005 and
May 2005 links at:
http://www.unidata.ucar.edu/community/seminars/

We are hoping to be able to distribute the QPESUMS products when they
are ready...but I haven't heard an update on the status recently.
