oggm.tasks.apparent_mb_from_linear_mb

oggm.tasks.apparent_mb_from_linear_mb(gdir, mb_gradient=3.0, ela_h=None)[source]

Compute apparent mb from a linear mass-balance assumption (for testing).

This is for testing currently, but could be used as alternative method for the inversion quite easily.

Parameters
gdiroggm.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.

linear_mb_params.pkl

When using a linear mass-balance for the inversion, this dict stores the optimal ela_h and grad.
