Pre-installation Program Options

The following optional, but highly suggested, programs should be installed prior to installing the full (registered) version of HYSPLIT. The trial version installation already includes Tcl/Tk, Ghostscript, and Info-Zip and they do not need to be reinstalled prior to installing the registered version over top of the trial version. The following are updated links and will also be provided on the distribution CD:

            Installation to different directories may require editing: \guicode\hysplit4.tcl.

HYSPLIT self-installing executables

Two version of PC HYSPLIT are available and can be downloaded from the HYSPLIT website:
  • setup47U.exe (46 Mb) – trial version, does not support forecast data
  • setup47R.exe  (16 Mb) – registered version requires web site registration
It is recommended that HYSPLIT be installed in the C:\hysplit4 directory, however it can be installed in other locations. This document will assume HYSPLIT is installed in the C:\hysplit4 directory.
