Re: 20050812: IDV version 1.2 available for download

Hi-

Jiang, Weidong [RA] wrote:


I tried the IDV version 1.2 using Java WebStart on my home PC (Windows XP).
When I tried to load a grib file from the local hard drive, I got the
following message.  The grib file is available at
https://atmos.saic-ine.com/gmt/19960420000000.grb.

I suspect the error is related to using incorrect grib table for this file.
I probably need to configure or point the IDV to the correct grib table.
Could you point a sample grib file that worked in IDV version 1.2?


You are correct that we do not have the tables in the IDV for the
FNMOC grids at sub-center 42.  We are working on generating tables
for that.

You can access a sample GRIB file that does work from NCEP:

http://nomad2.ncep.noaa.gov/pub/gfs/gfs20050829/

(not the .inv files).

We will be documenting the method of adding your own tables
in the next release.

Thanks,
Weidong Jiang
