Hi,

I have been using the HYSPLIT model for back-trajectory modelling starting in the Antarctic sea ice. Trajectories run back over the continent and output plots have elevation plots with a y-axis of Metres AGL. My question is whether this AGL accounts for the Antarctic ice-sheet, or whether it is for an ice-free surface? I would expect it to be the former, but want to double check since some data comparisons aren't making much sense.

An example trajectory is October 2012, starting at 65S, 120S

Thanks

The terrain height is given by the underlying meteorological data you are using to run hysplit.
