Trajectories of air parcel motions in Mars' atmosphere computed using HYSPLIT.

The HYSPLIT model has been adapted to compute trajectories of air and dust particle motions in the Martian atmosphere. We use winds generated by the NASA-Ames Mars General Circulation Model as input to HYSPLIT. Trajectories of air parcels emanating from the Hellas region during the MY25 dust storm will be examined in an effort to “follow the dust”. Later we will examine backward trajectories to estimate the origins of surface dust at high latitudes.
