Re: inline HYSPLIT
Dear members,
I am testing WRF-HYSPLIT for a trajectory run over Southern Africa with a 9km x 9km grid.
The model is producing wrfout files with the following variables :
float HYOLAT(Time, maxpar) ;
float HYOLON(Time, maxpar) ;
float HYOHGT(Time, maxpar) ;
float HYCSUM(Time, south_north, west_east) ;
However, none of them contains other values but zeros. Could you kindly help me spot what I'm doing wrong?
Below are my CONTROL and namelist.input files for reference.
Thanks in advance,
Genito Maure

Re: inline HYSPLIT
Since you turn on the trajectory run, there is no dispersion calculation (zero values for HYCSUM).
Search the WRF log file (rsl.out.0000) with "traj=". You should see the print out of lat/lon/height for the trajectory at each WRF time step. If not, the trajectory was not calculated. A lot of diagnose print out in the rsl.out.0000. Would you please send your rsl.out.0000?

Re: inline HYSPLIT
The search for "traj" (there's no "traj=") in rsl.error.0000 gives me the following warning:
My rsl.error.000o is too big to be attached here. so I sent it via email.

Re: inline HYSPLIT
The HYSPLIT calculaton is not called at the WRF's initialization step. Because some required met data for HYSPLIT calculation is not available at that time step. And we usually start the WRF model before the HYSPLIT for spin-up during the 1st few hours.
In your simulation, the HYSPLIT starting time was set to Aug 15th 00 UTC. The 1st WRF loop (Aug 15th 00 UTC+ 60 sec) has passed HYSPLIT's starting time. No trajectory calculation was done that is why you found zero values for HYOLAT, HYOLON and HYOHGT.
The solution is to set the trajectory to start at a later time (after Aug 15th 00 UTC in your case) or begin the WRF prior to desired trajectory starting time.

Re: inline HYSPLIT
Thanks a lot!
Your help is really appreciated. I managed to get HYOLAT, HYOLON and HYOHGT in my wrfout file.
Kind regards,
GMaure
