Dear all,

I am using the download version of Hysplit to calculate back trajectories with a script and I am getting files like attached. Since I see that is not calculating the height of the boundary layer, I would like to calculate it. Is that possible? How can I obtain the height of the boundary layer for each point? I would like to modify the script so that the trajectory calculation ends when the trajectory height exceeds the height of the top of the boundary layer. Is there any way to do it?
I am using the GFS 0p25 met data.

Thank you very much,

Jordina

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 available to be added along trajectory.

Thank you very much for your answer. How could I make that the script I am using to calculate the trajectories add also the height of the boundary layer to the outputs? Is there any available example?

Thanks again,

Jordina
