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 ...

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 ...

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 ...

I can confirm the same problem with the latest version and the same input files:

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:

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 ...

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.

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:

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 ...
