Scripts for dispersion
Hello: I am new with Hysplit and I saw there are some scripts to work in windows using the CMD with multiple trajectories. Are there any scripts for dispersion? Thank you.

Re: Scripts for dispersion
Most sections of the HYSPLIT tutorial provides scripts. For example, Sec. 9.3 titled "Turbulence Parameterizations" (accessible at https://www.ready.noaa.gov/documents/Tu ... _turb.html) provides a Windows PC script for running several dispersion runs: click the gear icon under the section heading.

Re: Scripts for dispersion
Hello, I see that you use a oct1618.BIN file as a met_file. What should I use if I want to get my dispersions from other coordinates and dates? What file(s) should I use as met_file? Thank you.

Met data files for HYSPLIT may be downloaded from ARL websites. Archived data for past dates are available at https://www.ready.noaa.gov/archives.php. Forecast met data files are available at https://www.ready.noaa.gov/READYmetdata.php. Please examine each meteorological datasets and use one that most suits your needs. Probably you might want to try several met datasets to gauge uncertainties.

Re: Scripts for dispersion
Hello: Yes, I have to run HRRR and I see each file has 5 hours per day, so If I want to run 48 hours, do I need to get 9 files and add all of them to the GUI? I run first a fw trajectories for 20 days and I got *.BIN files, shouldI use that one? or should I use the *.TXT file with the tdp inside?
