HYSPLIT Basic Tutorial Contents

Last Revised
February 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. The tutorial has been tested with HYSPLIT revision 802.
