In your Daily_Test_3.bat file, there are tabs in the "echo to the CONTROL file" lines. Change those tabs to spaces, then it will work. That makes a CONTROL file without tabs at the end of the lines.

After looking at the GUI code, this 'run daily dispersion' option is not configured for backward runs. You can develop your own scripts/batch files to loop through the dates/times. There are examples in the C:\hysplit\examples\scripts directory. See also section 2.4 in the Online Tutorial at https:/...

The meteorology is linearly interpolated in both space and time.

You can download HYSPLIT, the meteorology data, and through the HYSPLIT GUI, run a month at a time. Please see the online tutorial at https://www.ready.noaa.gov/HYSPLIT_Tutorials.php. Section 6.1 describes the "run daily menu", which you could use. The prior trajectory sections should also give you ...

The clusters are determined from the endpoint latitude and longitudes, not the heights. The heights, but not pressures are carried through to the output. For example see the file C1_5.tdump (open in Notepad), which is what is used for the Cluster 1 of 5 plot you show. There is a latitude, longitude,...
