Concentration model non-existent LANDUSE.ASC

[lourenco]

Hello, I am new to HYSPLIT and I'm encountering an error while running HYSPLIT version 5.3.0 (unregistered) on my macOS 14.5 system. I am running tutorial 2.3 Test Air Concentration Calculation. The model starts but then fails with the following error message:

It appears to be an issue with accessing the file LANDUSE.ASC in the /bdyfiles directory. The error message indicates a "severe (36): attempt to access non-existent record." The LANDUSE.ASC file is in my bdyfiles directory and is not corrupt (i can open it in a .txt file and see a bunch of numbers in a grid like pattern). Also the trajectory test works.

Has anyone encountered this issue before or have suggestions on how to resolve it? Any help would be appreciated!

The error occurred while reading the LANDUSE.ASC file. Probably this might have happened because 1) there is a mismatch in the number of data points between LANDUSE.ASC and ASCIDATA.CFG, or 2) LANDUSE.ASC is truncated. Could you open a terminal, change directory to your bdyfiles directory, and run the md5 command with the following files and see if the resulting checksums match those shown below?

$ md5 ASCDATA.CFG
MD5 (ASCDATA.CFG) = a472762b6c25215cebff8fa142ace10a
$ md5 *.ASC
MD5 (LANDUSE.ASC) = a55517b6a003fcdabb302cd6147e3645
MD5 (ROUGLEN.ASC) = dd17e02497bc6847c1bfdb4ecc0b4490
MD5 (TERRAIN.ASC) = 08749fe0ab1ee4c640d0d737e4321b25

I am having an identical issue to that of @lourenco. When I ran the md5 commands in the bdyfiles directory as @sonny.sinn suggested, I got the exact same resulting checksums listed in their posts. Are there any other suggestions on how to fix this issue?

Hi, I have the same problem. The checksums match. Any help on what may be causing this crash is greatly appreciated.

I am currently experiencing this issue on MacOS. I am also trying to do the tutorial: 2.3 Test Air Concentration Calculation. I tried removing those *.ASC files to unblock me, but then I get a new failure:

We confirm that HYSPLIT executables does not work with macOS Ventura 13.7.3 and probably with those released after Ventura, for example, Sonoma and Sequoia. We are looking into building new HYSPLIT distributions to address this issue.
