If my interpretation is incorrect and the trajectory model does not account for PBL mixing, as suggested from Stein et al., 2015 , then:
1. Should trajectories not be relied on once they hit the surface (unless using an ensemble approach)?
2. I presume that surface roughness is not considered either ...

Hello,

I’d appreciate your input on a few questions related to trajectories initialized at or near the surface:

1. Reading through the HYSPLIT user guide PDF and tutorial sect. 4-6, I understand (mostly implicitly) that the trajectory model in its recent versions applies a PBL mixing scheme (I ...
