HYSPLIT for Linux - Public (unregistered) Version Download
For details on the currently available version see HYSPLIT Updates.
What is available for downloading
The contents of this public unregistered version include various HYSPLIT executables and scripts. The unregistered version is identical to the registered version in all respects, except that the dispersion calculation will not work with forecast meteorological data fields.
The package also contains all the documentation and test data. However, the Tcl/Tk software to run the graphical interface must be independently downloaded and should be installed prior to installing HYSPLIT. A version that has been tested with HYSPLIT is available here for convenience. More recent versions, including registration information, can be obtained from the main site listed below.
The graphical user interface - Tcl/Tk
Although not required to run HYSPLIT, a GUI composed of multiple Tcl/Tk scripts are provided with HYSPLIT. The model can also be run using a command line interface. However, it is easier for novice users to use the Tcl/Tk interface. The standard HYSPLIT installation includes all the GUI scripts, but the Tcl/Tk interpreter is not part of the distribution. Most Unix / Linux operating system distributions, as well as macOS, include Tcl/Tk. If not already installed, you can download Tcl/Tk from the Tcl/Tk web site. Install the software to the suggested default directory prior to installing HYSPLIT.
