NaN in tdump file

[croc]

Dear Hysplit forum,
I am getting NaN fields for lat, lon and height running hyts_std v5.3.2 for
linux.

Can this problem be fixed in some way?

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 1 1 -274 -2970360.50 7.91646385 1.00000000
NOTICE main: 64319005 1 1 -275 -2960726.00 112.302284 0.655598700
NOTICE main: 64319004 1 1 -276 -2919918.25 3277.06274 1.00000000
NOTICE main: 64319003 1 1 -277 NaN NaN 1.00000000
NOTICE main: 64319002 1 1 -278 NaN NaN 1.00000000

If I understood correctly the file format, 278 should be the minutes
spent from the beginning of the trajectory, which corresponds to 4.6 hour,
close to the 5th hour where the NaNs make the first appearance in the
tdump file.

Since the warning message is written by the grdsiz routine,
could it be related to this
viewtopic.php?f=12&t=2785&p=7861#p7861
other problem?

Stefano
