Re: yearly record of trajectories

The PC/Mac GUI includes an option to run trajectories for multiple months - Trajectory - Special Runs - Daily. The code and meteorology may be downloaded via https://www.ready.noaa.gov/HYSPLIT.php. Please see the tutorial at https://www.ready.noaa.gov/documents/Tutorial/html/index.html, in particula...

Re: Deposition plots

At level 0m the values are deposition, not concentration.

Re: Eddy diffusion in back trajectory?

The trajectory calculation uses the mean wind resolved in the meteorological model. For finer scale eddy motion you cannot use these trajectories.

Re: Single Particle Animation Error

I meant did you verify concplot.ps is as expected? Did you view it and all the images are ok? In Notepad, open the file C:\hysplit4\working\default_exec. When you went in "Set Directories" through the GUI, that is the file that you are changing. Verify it has C:/Program Files/ImageMagick-7.0.4-Q16/c...

Re: Eddy diffusion in back trajectory?

The Basic Tutorial explains the trajectory calculation. https://www.ready.noaa.gov/HYSPLIT_Tutorials.php It is advection only. Per the Tutorial, single trajectories have limitations, hence there are options for an ensemble, starting trajectories with time, etc. For a cloud, you would need to start b...

Re: Single Particle Animation Error

Are you saying you got the same error with both of the following in the "Set Directories"? convert.exe C:/Program Files/ImageMagick-7.0.8-Q16/convert.exe Try it again after exiting the GUI and restarting it, and make sure the Set Directories has the full path (C:/Program...). Did you verify the post...

Re: concentraton-vertical

There is not a program to output a vertical concentration section. You need to run HYSPLIT outputting concentration by layer. Then run con2asc or con2stn. Particle plots can show vertical cross-sections.

Re: Concentration Display in HYSPLIT4

The plot failed. The "Concentration Display" window in the first line shows the input file is named "cdump". Does that file exist and is its size >0? If yes, then run the program through the GUI Concentration / Utilities / Simple Listing, choosing the file "cdump". That will show you information on ...
