We don't know exactly what is in the ash, so approximations are made. In that GUI section, first do a run choosing Particle, and no wet, no dry deposition. Save the CONTROL file for reference. Then add dry deposition, which will give a value for the deposition velocity. Then add wet deposition.

The map domain is defaulting to the whole plume, even though you are forcing the higher contour values. Have you tried the Google Earth option? concplot ... -a3 If you want concplot, run concplot.exe in the command prompt, and it will show all the options. Try the -h and -g options forcing 0 circles...

Please send your CONTROL and SETUP files for these runs, and the command line for the program that outputs your values shown.

Because it is working in the Execute Display in the GUI, you need to make sure all those options are set in the command line equivalent. Looking at the "Create a Trajectory Frequency Plot" GUI window (Trajectory - Display - Frequency), you need to click "Polar" and set the zoom. Those are the only o...

We are working on an operational fix, then will need to fix the archived files. This applies to all the "nams" files.

See the help file c:\hysplit4\html\S417.htm. Or through GUI, Advanced - File Edit - Emissions File.

It does not. Further, the precipitation was revised to be 6-h accumulation for all the files in /pub/archives/gfs0p25.

You need to guess at a source location. Section 6.4 of the Tutorial, Source Geolocation, says the "forward trajectory ... encompasses the time period of the sampling." This is probably because the meteorology file(s) in the output CONTROL files will be the same as in this forward trajectory.

Ghostscript is usually in c:\Program Files\gs, and
Ghostview in c:\Program Files\Ghostgum

For a description of the output trajectory file (tdump), see

The trajectory implies the u and v components along the trajectory. We didn't choose that variable as one of the ones to output as a diagnostic variable.
