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 curre...
