Hello HYSPLIT user.
I want to run hysplit concentration model using WRF-ARW output file.
I already converted WRF-ARW file using arw2arl module.

Using ARLDATA.BIN(converted WRF-ARW data) i can simulate trajectory model.
But it doesn't work for concentration simulation model.

What should i do to use ARLDATA.BIN for concentration simulation of HYSPLIT?

P.S. When i use ARLDATA.BIN for concentration simulation, There is 'FORTRAN RUNTIME ERROR : Bad real number in item 1 of list input' occur.

Please help me to run hysplit.

I really need your help.

Would you please attach the CONTROL, SETUP, and MESSAGE file? Those can help us to diagnose the issue.
Since you can run trajectories with the met file, the problem is unlikely in the met file. It is probably in the CONTROL and SETUP.

Please attach the MESSAGE file. Only seeing one line is hard to know what is going on.
It seems the message indicating that particles go out of the meteorological grid. Was this happen at the beginning of the simulation? If so, you need to provide the met data with a larger domain. In the MESSAGE file, you can know how long the simulation ran until particles leaving the met grid.

You should have a SETUP.CFG file in your working directory. It is a necessary input file for running a dispersion simulation. The HYSPLIT online tutorial is helpful to learn how to setup and run the model:
And this is the section running a real dispersion case: ... _cexp.html
