Allow FVCOM tools to Update Ice Surface Roughness Length (#604)
Browse files Browse the repository at this point in the history 
* Update zorl for ice points in surface data file

* Change warm start ice roughness length variable name to zorli

* Change warm/cold start surface roughness var names in output nc file

* Include ice thickness processing

* Change ice roughness length from 1.0 to 1.1

* Zorli set to Fill_Value when ice is removed
