inline HYSPLIT

HYSPLIT was originally designed to run offline utilizing meteorological data such as are provided by WRF-ARW. A new model framework has been developed that the revised HYSPLIT model is coupled inline with WRF-ARW to take advantage of the higher temporal frequency of the meteorological variables produced by the meteorological model, as well as using WRF-ARW's vertical coordinate scheme. The inline coupling approach is a more consistent depiction of the state of the atmosphere available to the dispersion model through the elimination of the need to interpolate the meteorological fields temporally and vertically. This forum was created to foster discussion on the use of the In-line WRF-HYSPLIT coupling.

The inline version of HYSPLIT (coupled with WRF-ARW) is now available.

Re: inline HYSPLIT

Post by genito » September 9th, 2016, 6:10 am

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

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?

The search for "traj" (there's no "traj=") in rsl.error.0000 gives me the following warning:

Code: Select all

--- WARNING: traj_opt is zero, but num_traj is not zero; setting num_traj to zero.
My rsl.error.000o is too big to be attached here. so I sent it via email.

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.

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

Hi there,
My problems seems to be similiar, but I can not solve them by tempering with start date. I get HYOLAT, HYOLON, HYOHGT variables, but there are only zeros. Could you please give me some hints what is happening? I'm attaching my namelist.input, CONTROL and rsl.out.0000 files (there are no traj= lines).
Thank you in advance for any suggestions

It sounds the trajectory calculation was not started at all. Would you please show your namelist.input and CONTROL file?

Thank you for reply. Yes of course - I tried to attach control, namelist.input and rsl.out.0000 as zip file, but it seems it doesn't work.
Here is the control file:

Of course I have other sections too and the WRF model output seems to be ok.
The rsl.output.0000 have lots of lines similar to this section:

Re: inline HYSPLIT

It probably is because time_step=75 caused the mis-match of clock between HYSPLIT and WRF that no trajectory calculation was started. Refer to the post viewtopic.php?f=32&t=1158
The problem can be solved by changing time_step=60.
