2018 AMS HYSPLIT Short Course

A 1 day HYSPLIT short course will be given on Sunday, January 7, 2018, as part of the 98th Annual Meetingthis link opens in a new window of the American Meteorological Society (AMS) in Austin, Texas. The short course titled, “Using PC/Mac-based HYSPLIT for Basic Trajectory and Dispersion Applications,” is designed for novice HYSPLIT users and will be focused on the basic trajectory and particle dispersion calculation with each participant using their own PC or Mac (no Tablets/Ipad). Topics will include meteorological data sources required for the computations, the trajectory calculation, sources of trajectory error, and the use of multiple trajectories including cluster analysis. The generation of multiple particle trajectories to compute dispersion patterns and air concentrations will be reviewed, including the uncertainty introduced by the limitations of the meteorological data.
