[McIDAS #UGD-896576]: IMGREMAP of GOES-16 for use in GEMPAK



Hi Robert,

Hmm...  Have you tried displaying any of the Unidata-Wisconsin images (IDD
feed type UNIWISC aka MCIDAS) in GEMPAK?  If yes, do you see temperatures
for the IR images?

Note:

If you are not getting an IDD feed of UNIWISC images, you can grab some for
testing from:

http://atm.ucar.edu

  Decoded ldm data archives
  http://atm.ucar.edu/decoded/

    gempak/
    http://atm.ucar.edu/decoded/gempak/

      areas/
      http://atm.ucar.edu/decoded/gempak/areas/

        ...

All images are in PNG-compressed AREA format.  PNG-compressed AREAs are
usable in Unidata McIDAS-X, Unidata GEMPAK, the IDV and McIDAS-V.

Right.  McIDAS understands how to produce calibrated displays from the VISR
(1-byte) images that are created by IMGREMAP.

I don't know.  Again, can you check one or more Unidata-Wisconsin IR
images to see if it/they work in GEMPAK?

The difference might be in the calibration type of VISR.

re:
> Of course this could be something on the GEMPAK end as well..

Yes, exactly.  Let's start by testing one or more Unidata-Wisconsin
images.

Cheers,

Tom
