compass.landice.tests.ismip7_calibration.ais.melt_model.melt_from_tf

compass.landice.tests.ismip7_calibration.ais.melt_model.melt_from_tf(melt_form, parameter, fields, config, delta_t=None, mean_tf=None)

Recompute the melt field from the thermal forcing at the draft.

Parameters:

• melt_form ({'ismip7', 'ismip6'}) – Which melt form to evaluate

• parameter (float or xarray.DataArray) – K for 'ismip7' or gamma0 for 'ismip6'

• fields (dict) – From read_run()

• config (compass.config.CompassConfigParser) – Configuration options, for the constant salinity, slope and Coriolis parameter

• delta_t (float or xarray.DataArray, optional) – The basin correction to apply; defaults to the field the run used

• mean_tf (xarray.DataArray, optional) – Precomputed basin-mean thermal forcing, for 'ismip6'

Returns:

melt (xarray.DataArray) – Melt rate in kg m-2 yr-1, positive for melting, zero off the shelves
