Installing HYSPLIT on a Mac

The HYSPLIT Mac installation is similar to the PC except that the Mac OS supports the native display of Postscript files, therefore Ghostscript is not required. This version will only install under OSX 10.6.

1. Tcl/Tk Graphical User Interface

   Go to the Tcl/Tk web site to download the most recent Mac version.

   • Tcl/Tk Home Page
   
   
2. Postscript Converter

   On Mac systems Ghostscript is not required and therefore when using Preview, export the file to any non-Adobe format, which then can be converted to any other format using ImageMagick.

3. Postscript Viewer

   Not required. Use Preview, however, if there are too many Postscript frames in a file, Preview may have trouble converting the output to a viewable PDF. In this case you need to reduce the number of output frames in one file.

4. ImageMagick File Converter

   Go to the ImageMagick web site to download the most recent Mac version.

   • ImageMagick Home Page
   
   
5. Mac OSX 10.6 HYSPLIT Installation

   Download and open the installation package and HYSPLIT will be automatically installed in its own directory (Hysplit4) in your $HOME directory (user directory install) or in a system directory (root directory install). The Mac version was compiled under OSX 10.6 using the INTEL compiler. This version only installs and works under OSX 10.6.

   • User directory install (CD-ROM only)
   • Root directory install (CD-ROM only)
   • WEB download registered version

8. Starting the first time

   Once installed, open a terminal window or X-window and change directory to hysplit4/working. Then just execute the softlink hysplit4.tcl and the GUI should open if Tcl/Tk has been installed. The model should run in either terminal window. However, certain applications will only work from the X-terminal window. Once installed, insure that the X-directory location (usually /usr/X11/bin) in file default_exec points to the location of xterm, which can be determined from the command which xterm.
