Re: Interpreting Ensemble Results
I used the online HYSPLIT, so whatever the default is. I assume 1 grid cell but it is not defined in the online version.

Re: Interpreting Ensemble Results
I ran a trajectory at 3 heights, 10 m, 100 m, and 200m (see attached), using the met file 20210617_06-11_hrrr, the same met file used in the ensemble trajectory above. My question now is, what does the ensemble say about the trajectories I just ran? Are they ok or of questionable accuracy? traj-0617...

Odor Source Back Trajectory
. I am a regulator, and we respond to odor complaints. I often use trajectories to get an idea of which facility might be the odor source (this is independent of sending inspectors in the field). I run trajectories using online HYSPLIT with HRRR (archive or forecast) at a height of 10 m AGL (Jackson...
