If not already installed, you can download Tcl/Tk from the Tcl/Tk web site. Most Unix / Linux operating system distributions, as well as Mac OS X, include Tcl/Tk.

The HYSPLIT installation includes all the GUI scripts, but the Tcl/Tk interpreter is not part of the distribution. However, it is easier for novice users to use the Tcl/Tk interface. The model can also be run using a command line interface. Starting with HYSPLIT v5.2.0, the graphical user interface only requires Tcl/Tk because the Postscript graphics have been replaced by Scalable Vector Graphics (SVG) which can be displayed through any browser.Īlthough not required to run HYSPLIT, a GUI composed of multiple Tcl/Tk scripts is provided with HYSPLIT.

The HYSPLIT Mac installation is similar to a Windows PC.
