oggm.tasks.catchment_width_correction(gdir)[source]

Corrects for NaNs and inconsistencies in the geometrical widths.

Interpolates missing values, ensures consistency of the surface-area distribution AND with the geometrical area of the glacier polygon, avoiding errors due to gridded representation.

Parameters: gdir : oggm.GlacierDirectory where to write the data

Notes

Files writen to the glacier directory:
inversion_flowlines.pkl
A “better” version of the Centerlines, now on a regular spacing i.e., not on the gridded (i, j) indices. The tails of the tributaries are cut out to make more realistic junctions. They are now “1.5D” i.e., with a width.
