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.

George, I have completed the testing, and submitted code to the branch. This development is ready to go once reviewed on the review wiki?.

I have set up a testing wiki to describe the testing I have done

Many thanks

John
