Re: [gembud] GEMPAK 6.2.0 - blank local 1km base refl images

Hi Pete,

I think the culprit is in the $GEMPAK/source/gemlib/im/imsimg.f subroutine. Line 422 is commented out:

C                       imdoff = imdoff + ioff

If you uncomment this line, recompile the subroutine, replace its object file in the $GEMLIB/gemlib.a archive file, and then remake gpmap (or whatever program you are using to display the level 3 radar file) it will display the data in the DS.p94r0 directory that I assume you are referring to.

However, I suspect this will cause other radar files to not display . . . I suspect that the level 3 radar files must have differences in their headers, such that two different header lengths are found depending on the file.

Hope this helps at least temporarily . . .

Cheers,

Kevin

Hi again -

We are pulling 1km 0.5 Base Refl local radar data from http://www.nws.noaa.gov/tg/radfiles.html that although display properly in 5.10.4, 5.11.1 (NMAP2 or gpmap) do display no data in 6.2.0.

Interestingly the "blank" image DOES display the proper map background, image label, and color bar information. However there is no data on the image.

We feel there is a table setting we are not invoking but are unaware of going from 5.11.1 to 6.2.0.

We've even pointed 6.10.2 at 5.11.1 tables and still no luck. Just to clarify these are not nex2gini composites (which do display properly in 6.2.0), rather these are any local radar pulled from the site above.

If anyone has any insight on this, we'd love to hear it as we've been pulling our hair out most of the day testing seemingly innumerable adjustments in imgtyp.tbl and various lut files (even throwing Hail Mary's by testing changes in nidprod.tbl, and datatype.tbl).
