oggm.tasks.compute_downstream_line

oggm.tasks.compute_downstream_line(gdir)

Compute the line continuing the glacier.

The idea is simple: starting from the glacier tail, compute all the routes to all local minimas found at the domain edge. The cheapest is “The One”.

The rest of the job (merging centerlines + downstream into one single glacier is realized by init_present_time_glacier()).

Parameters:

gdir : oggm.GlacierDirectory

Returns:

Files writen to the glacier directory:

downstream_line.pkl

A dict containing the downsteam line geometry as well as the bedshape computed from a parabolic fit.
