oggm.tasks.local_t_star(gdir, *, ref_df=None, tstar=None, bias=None)[source]

Compute the local t* and associated glacier-wide mu*.

If tstar and bias are not provided, they will be interpolated from the reference t* list.

Note: the glacier wide mu* is here just for indication. It might be different from the flowlines’ mu* in some cases.

gdir : oggm.GlacierDirectory

the glacier directory to process

ref_df : pandas.DataFrame, optional

replace the default calibration list with your own.

tstar: int, optional

the year where the glacier should be equilibrium

bias: float, optional

the associated reference bias


Files writen to the glacier directory:
Some information (dictionary) about the mass balance parameters for this glacier.
A dict containing the glacier’s t*, bias, and the flowlines’ mu*
