method_Moelg

cosipy.modules.roughness.method_Moelg(GRID)

Update the roughness length.

Adapted from Moelg et al. (2009), J.Clim. The roughness length of snow linearly increases from 0.24 (fresh snow) to 4 (firn) in 60 days (1440 hours) i.e. (4-0.24)/1440 = 0.0026.

Parameters:

GRID (Grid) – Glacier data structure.

Returns:

Surface roughness length, [mm]

Return type:

float
