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.

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.

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:

https://hysplitbbs.arl.noaa.gov/

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:

https://hysplitbbs.arl.noaa.gov/viewtopic.php?f=3&t=1161&p=3108&hilit=Ntwali#p3108

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

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.

Hello Ntwali,

See: https://hysplitbbs.arl.noaa.gov/viewtopic.php?f=3&t=1161

Hopefully that post addresses your question.

Best,

Thank you so much for your advices and guidance. I really appreciate your kind help.

I have followed all steps and now it works.

Again thank you.
