We are running backward trajectories using WRF model input at different heights. We are wondering if Hysplit uses full models from WRF and interpolates where there is not a full level. Is it?
In addition, if we order Hysplit to calculate the trajectory at 2 m, and we know that the first level of WRF is at 8 m, what is Hysplit doing? Is it giving the trajectory at the first full level?
Many thanks in advance
Trajectory heights from WRF
Re: Trajectory heights from WRF
HYSPLIT does the interpolation between layers. If you set the starting height of the trajectory at 2 m, HYSPLIT starts the trajectory calculation at 2 m above ground level (terrain height from WRF).
Re: Trajectory heights from WRF
Thank you, but what does it do if the first level of the model is at 10 m?
