oggm.tasks.mu_star_calibration

oggm.tasks.mu_star_calibration(gdir)[source]

Compute the flowlines’ mu* and the associated apparent mass-balance.

If low lying tributaries have a non-physically consistent Mass-balance this function will either filter them out or calibrate each flowline with a specific mu*. The latter is default and recommended.

Parameters:
gdir : oggm.GlacierDirectory

the glacier directory to process

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.
