Hi, I am running the concentration model on a macOS 13.2.1. I define particle species with dry and wet deposition on, by defining non-zero diameters, densities and shapes (all our pollutant deposition parameters set to zero except in-cloud and below-cloud). I was having this error: forrtl: severe (3...

Hi, I have the same problem. The checksums match. Any help on what may be causing this crash is greatly appreciated.

I'd like to run HYSPLIT simulations using a paleoclimate grid. Since CMIP6 does not have paleoclimate simulation data at sub-monthly resolution, I'd have to run my own simulation, say with CESM2, with 3-hourly resolution for example, and save the variables required by HYSPLIT. I'd just like to ask i...

Hi! I'd like to perform HYSPLIT trajectory and dispersion simulations using a meteorological derived from a paleoclimate simulation. I've checked CMIP6 data but the available time resolution for paleoclimate simulations is monthly at best. I would thus have to run my own simulation and save the data...

Hi community, I need to run one back-trajectory per hour, each lasting six hours, from a single point, during a full year. After setting up the parameters on the trajectory's Setup Run menu, I manually modify the CONTROL file, adding "1 60" in one of the lines (1: one single resolution met file, 60:...

Hi, I am running multiple trajectories using the "Special Run -> Daily" routine, and then display a map of trajectory frequencies. Is there any way to convert the data used to plot this into ASCII so as to work with it in other programs? There is the "Concentration -> Utilities -> Convert to -> ASCI...

Hello! I tried to follow these steps to download compiler Active Tcl 8.5, but it is no longer available for free. If anyone knows where I may get this version or some other compiler that allows me to use Hysplit's GUI in macOS Monterey, please let me know.

Thank you for the link. I followed the steps that the previous user suggested. However, the necessary Tcl compiler to make Hysplit's GUI work for macOS Monterey (ActiveTcl 8.5) is no longer available for free at the website mentioned by the previous user. In case someone knows where I may get it, le...

Hello, I am trying to install v.5.2.1 to my Mac (v. 12.2.1 - Monterey). I believe I have correctly installed Tcl/Tk, then Hysplit, but when I open the GUI the screen is black (although I do see the Exit, Help and Menu buttons). Maybe there is a known issue with my Mac version?

But, Ariel, wouldn't that imply that the full area of each grid cell is assumed to emit dust? Isn't it that only a fraction of the area of each grid cell is assumed to emit dust? I've read in Draxler et al. (2010), in section 2.4, that that fraction of the grid cell is calculated based on Ginoux et ...
