Hi,
I have a WRF model output data over the domain size on 100kmX100km. I would like to plot the trajectories over every 5 mins, but the default option for plotting the 1 hr. I am just wondering if is it possible to plot the trajectories for every 5 mins interval. I am aware that in the advance set up of hysplit we can provide the time integration step in mins, but could it be possible to plot the trajectories after every 5 mins interval.

Thanking Yours,
Shanky

No, the minimum symbol display option is 1 hour.

Hi,
Is there any way so that I can modify the source code and recompile it in order to plot the trajectory for every 5 mins or whatever time interval i desired. Or is there any other way I can store the output data in text format (for every 5 mins interval) so that I can use some other plotting utility to plot the trajectories ? For example, for the dispersion runs the data can be stored into the text files.

Thank You

You can set the trajectory output frequency to 5 minutes in the Advanced/Configuration Setup/Trajectory #4 option "Trajectory points OUTPUT FREQUENCY" and they will be written at the entered frequency into the tdump text file which you could then import into another display program. If you wanted to try to modify the current trajplot.f program, the section that plots the endpoint positions is in the hysplit4/library/hysplit/trjmap.f program and the variable is called KTHRS.
