https://github.com/lhenneman/hyspdisp/blob/master/vignettes/hyads.Rmd#L243 Here we do not specify the duration_run_hours and here https://github.com/lhenneman/hyspdisp/blob/master/R/hyspdisp_zip_link.R#L5 it is 240 by default. I would like to explain what it is to the user but I have trouble understanding this myself.

How is it related to here? https://github.com/lhenneman/hyspdisp/blob/master/vignettes/hyads.Rmd#L196

Hey Maja,

Yes, all those are related. duration_run_hours specifies the number of hours that HYSPLIT tracks each air parcel. We've always used 10 days, i.e., 240 hours. I think 240 should definitely be the default, but users should have the option to change it if they wish. I agree it could be documented better.

Just in case you're interested (and maybe to add to the documentation), 10 days is the maximum (give or take) that sulfur stays in the atmosphere before it deposits to the ground.

Does this make sense?
