Hi Ntwali,

As far as I know, instead of using GUI, you can use the SplitR and opentraj packages in R for running numerous simulations. https://github.com/rich-iannone/SplitR/SplitR 

Hi Xuezhi,

Thank you for your advice and to inform me about SplitR software.

Unfortunately I'm not familiar to run air particles trajectories using that software, that's why I want to use HYSPLIT model.

Kind regards.

Hi Ntwali,

SplitR is just a package for preparing input data and for HYSPLIT model and automatically run many simulations. SplitR is not a trajectory model. HYSPLIT model can only be run in batch mode if you want to run numerous simulations. GUI can run only one simulation at a time. Hopefully, you can understand what I say.

Hi Xuezhi,

Thank you for that helpful explanation. I will try and I hope I will be able to use SplitR.

Thank you so much.

Greetings,

Please send your question to the HYSPLIT forum:

The Air Resources Lab keeps a log of these sorts of issues to help others with similar questions.  The team should provide a quick response for you.

Thank you,

Rick

Dear Richard Artz,

Thanks for your advice. Unfortunately I sent this problem to the HYSPLIT forum last month and up to now I didn't receive any answer/suggestion/help.

I will try again.

Thanks

Hello,

The response was posted last month at:

Let me know if you're still having problems accessing it.

Dear Richard Artz,

I really appreciate your kind help. I have asked again the forum for help today, where I mentioned that after putting NCEP data of 3 months (March-April-May) in the trajectory setup in order to run MAM season backward trajectory, I keep getting the trajectory of May not for the 3 months together (MAM). I order words it seems that by combining many months the output trajectory is only for the last month.

Hope to hear from your help and guidance.

Kind regards.

Ntwali

 Hello Ntwali,
