A new snow thermodynamic scheme for large-scale sea-ice models
This paper assesses the capabilities of a new one-dimensional snow scheme developed for the thermodynamic component of the Louvain-la-Neuve sea-Ice Model (LIM). The model is validated at Point Barrow, Alaska, and at Ice Station POLarstern (ISPOL) in the western Weddell Sea, Southern Ocean. The new s...

This paper assesses the capabilities of a new one-dimensional snow scheme developed for the thermodynamic component of the Louvain-la-Neuve sea-Ice Model (LIM). The model is validated at Point Barrow, Alaska, and at Ice Station POLarstern (ISPOL) in the western Weddell Sea, Southern Ocean. The new snow thermodynamic scheme leads to better snow internal temperature proï¬les, with a set-up-dependent increase in the correlation between simulated and observed temperature proï¬les. On average over all runs, these correlations are 27%better with the six-layer conï¬guration. The model’s ability to reproduce observed temperatures improves with the number of snow layers, but stabilizes after a threshold layer number is reached.
