2-1PC-HYSPLIT WORKSHOP
Part 2: Trajectory Methods
Example SimulationsExample Simulations
Now that you’ve had a chance to run a few more difficult trajectory analyses, you can run through the following examples that include simple and more complex simulations prior to viewing the next few sections of the workshop.
The first slide of each example will present the problem to be answered, the next few slides will show the GUI inputs, and the last slide will show the resulting map.
It is recommended to click on the Reset button of the main HYSPLIT menu before proceeding in order to clear out any old cases in the working directory.
Note: These runs were produced using HYSPLIT version 4.9 (released January 2010). Slight differences are possible with older/newer versions of the model.
