Dear Hysplit forum, I think I have a clue to locate the bug. The problem might be associated with the following warning i get during the execution: WARNING: advpol.f could not move off pole point Moreover, I am getting NaN also in MESSAGE. The following is where the NaN starts: NOTICE main: 64319006...

Dear Hysplit forum, I am getting NaN fields for lat, lon and height running hyts_std v5.3.2 for linux. CONTROL file content is: 22 04 17 04 1 #NUMBER OF STARTING LOCATIONS -89.997 -24.8 10 #STARTING 1: LATITUDE LONGITUDE HEIGHT (m-agl) -240 #TOTAL RUN TIME (backwards) 0 #VERTICAL MOTION CALCULATION ...

Dear alicec, thanks for your considerations and suggestions. I am presently calculating backtrajectories reaching the soil around the South Pole. I have already planned to implement the automatic download and conversion of ERA5 meteo files, which I tested a few months ago. I will keep in mind the ne...

Dear alicec, thanks for confirming the error, the valuable suggestions and the fix you are working on. As a matter of fact, setting DELT=1. does allow to propagate the problematic trajectory. Nevertheless, I was quite worried by your considerations about the vertical motion methods. I actually notic...

I can confirm the same problem with the latest version and the same input files: HYSPLIT - Initialization HYSPLIT version: hysplit.v5.3.2 Last Changed Date: 2024-02-01 NOTICE: using namelist file SETUP.CFG *WARNING*: metini - vertical velocity missing, switching to divergence Input data file: 1 1 GH...

Dear Hysplit user Forum, I think I might have found a bug in the hyts_std code v. 5.3.0 for linux. Computing backtrajectories for South Pole station using GDAS 0.5 meteo files I get the following at the standard error: HYSPLIT - Initialization HYSPLIT version: hysplit.v5.3.0 Last Changed Date: 2023-...

Dear hysplit user forum, I am having problems running hysplit using meteo files from 20090317_gdas0p5 to 20090329_gdas0p5, obtaining NaN values in tdump files. My guess is that the problem is related to the missing/filled in fields in meteo files as stated in readme_gdas0p5_missings.txt: 2009 March ...

Thank you sonny.zinn.
Sorry for not having checked the readme_gdas0p5_missings.txt. I did not
expect to find a file with just some of the needed fields.
Regards,

Dear hysplit user forum, I think I found a problem in the header of the meteo file 20090504_gdas0p5. hysplit version 5.2.0 crashes reporting the error: At line 339 of file metinp.f Fortran runtime error: Bad value during floating point read whereas chk_data gives: Opened file : 9 5 4 0 Grid size and...

Dear hysplit user forum, I think I found a problem in the file 20080427_gdas0p5 which apparently is a duplicate of 20080426_gdas0p5 since the two file are identical and chk_file returns: File start time: 8 4 26 0 0 File ending time: 8 4 26 21 0 Could you please confirm the problem? Is there any chan...
