Support GOES 19

[akrherz]

Likely need to review the various GEMPAK code and tables to see what needs added to support GOES 19, which became operational goes east today!

[vgensini]

I assume that is why all my GOES-16 scripts failed around 15z on 7 April?

E.g.,

UNIWISC ^pnga2area Q. (CNC02) (.*) (GOES-16)_IMG (.*)um (.*) (........) (....)
        EXEC    /home/scripts/gempak/sat/vis/vis.csh \6_\7

I see 1 and 2km products coming in on the UNIWISC feed for GOES-19, so that is good. I am assuming I cannot just try to use those same files in my G16 scripts? The tables would be different as you mention...

[mzuranski]

You should definitely try... but I'm thinking that GOES-16 pattern wouldn't work anymore. Paste any errors you come across here please!

[IM 1] No entry in the image type table, imgtyp.tbl, for file /home/ldm/data/gempak/images/sat/GOES-19/CONUS/1.0km/0.64_2025041

Checking out imagetyp.tbl to see if I can band-aid.

[mzuranski]

That helps!

What I would try is to copy an existing section, GOES16 makes sense to me, and duplicate it for GOES19: https://github.com/Unidata/gempak/blob/aaaaa35500cf54f38c24127e413dfb1f4287b265/gempak/tables/sat/imgtyp.tbl#L296C1-L326C82

[vgensini]

Yep, exactly what I was thinking.

[vgensini]

Ok, seems to be working over here.

In $GEMTBL/sat/imgtyp.tbl you'll want to copy all GOES-16 entries, change the prefix to GOES-19 _and change the SAT ID number to 192. Example for visible channel 2:

GOES19 CH02 VIS_0.64 0 255 192 2 1 GRAY

Thanks to @mzuranski for finding the SAT ID number. Still working to figure out the SAT ID number for the RGB products.

EDIT: Seems to be working, BUT, there are large changes in the projection. E.g., See the attached ani gif.

[mzuranski]

@vgensini Based on what I see from imgtyp.tbl, GOES-19 RGB should be 393 based on the following:

GOES16 RGB           AIRMASS       0     94    390
GOES17 RGB           AIRMASS       0     94    391
GOES18 RGBABI[sic]        AIRMASS       0     94    392

Any chance you could test GOES19 RGB value 393 and report back?
Much appreciated!

Ahh genius! I did not think about changing the SAT ID number, so much thanks to you all for this. Now mine works properly.

[akrherz]

Somebody PR this or it didn't happen :)

[vgensini]

PR-created :-)

[russ-schumacher]

works for me too - thanks so much @vgensini and @akrherz !

[mzuranski]

@vgensini Thanks for being the test subject for this, and thank you others for reporting in!

@akrherz With #163 closed I'm thinking we should close this as well.
