Re: Cluster analysis PC/Python

If you used the hysplit program 'trajplot' to plot your python trajectories, the cluster program will work. The cluster file INFILE is a listing of all the trajectory endpoints filenames. It is in your working directory (generally c:\hysplit4\cluster\working or c:\hysplit4\working). If there is noth...

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...
