Description
The current stretched sigma coordinate options mean the size of the surface box varies greatly, leading to inconsistent flux inputs. A terrain following coordinate system which still provides a constant surface box height has been developed.
This has been tested in a series of test configurations based upon a shelf model the AMM7 and shown to improve air-sea exchange and reduce pressure gradient errors.
