There are couple of reasons that HYSPLIT resets Z_FLAG to 1 even you use WRF files with Z_FLAG=5. One of them is WVERT=false or being reset to false. Your message file shows WVERT=F. So, set WVERT=true in SETUP.CFG.

Go to "[HYSPLIT directory]/data2arl/arw2arl" and then type "make". The executable will be regenerated in [HYSPLIT directory]/exec.
Make sure to put the right directory path to the corrected NetCDF library in Makefile.inc in your [HYSPLIT directory].

The problem is due to WRF output files do not have consistent time intervals as shown in program log when you ran arw2arl =>
0.00000000 2016-01-01_00:00:00
62.0999985 2016-01-01_01:02:06
121.500000 2016-01-01_02:01:30
Output time interval not constant

I can process a WRF file with polar project and diff TRUELAT1 and TRUELAT2. The converter works by adding "plat=tlat" before the if statement. You may print out tlat and plat to make sure they are set to the same values (TRUELAT1).

IF(iproj.EQ.2)THEN
plat=tlat
print*,tlat,plat
IF(TLAT.NE.PLAT ...

Please try the following:

1) Delete the old ARLDATA.CFG when you process WRF files that have different map projection from your previous run. The WRFDATA.CFG file is a list of WRF variables matching HYSPLIT required variables. It has nothing to do with WRF's domain configuration and map projection ...

The inline HYSPLIT coupled with WRF uses the HYSPLIT code prior to v5.0.0 (https://www.arl.noaa.gov/hysplit/hysplit-model-updates/). It is HYSPLIT revision 700-800. All the revisions up to v4.2.0 are relatively minor in terms of the coupling approach. However, we have major updates and changes ...

You can add meteorology output along trajectory including boundary height.
Please see the HYSPLIT tutorial 5.3 as an example which is for adding terrain height.

And the HYSPLIT users' guide has the list of variables that are ...

Another check is ... was your netcdf library compiled with the same compiler used to install HYSPLIT?

I was able to convert your wrfout file successfully, running with the Linux and PC version. You may need to check your netCDF library.
