HYSPLIT Basic Tutorial Contents

Last Revised
December 2016



Follow the HYSPLIT tutorial sections in the sequence shown below, working through each example. GUI menu screen images will be shown as needed. However, not all of the GUI options will be exercised with each example. Additional menu options will be introduced as needed. Some menus have a zoom button to show the required data entry values in a larger type. The tutorial is focused toward running HYSPLIT on a Windows PC. However, most sections have a link to a LINUX script or a windows batch file that can be used to reproduce the example. The GUI just creates the required input files needed to run HYSPLIT. Although the operation of the GUI is similar on Linux and Mac platforms, not all of the GUI functions are available on all systems. If you are going through this tutorial from the DVD, some of the examples will go faster if the contents of the DVD are copied to your hard drive (c:\Tutorial). Meteorological data required to run the examples are on the DVD but only data for the basic examples are available on-line. The tutorial has been tested with HYSPLIT revision 802.
