Hello,
I would like to ask if it is possible to generate trajectories for many hours, for a few days, but for one location and one height, in one inline-HYSPLIT run? If it is possible, I'd be very grateful for answer: how to do it?
All the best,
Daria

For the inline system, once a trajectory is launched during the middle of a WRF run, it will continue for hours or even days until the WRF simulation ends. You can start multiple trajectories at the same starting time. To run trajectories starting at different hours or days, you can use standard HYSPLIT (offline) driven by the WRF data you generated.

The benefit of using inline HYSPLIT is for dispersion simulations in a fine spatial and temporal resolution. A trajectory calculation only has advection component which is not that sensitive to the couple approach. For trajectory runs, you probably should go with standard HYSPLIT which has more features serves different applications.
