Description of changes
The CMEPS will be updated to transfer ocean-current fields from MOM6 to WW3 and to transfer the Stokes drift components from WW3 to MOM6 for the HAFS applications.
Specific notes
The interpolation method used for the ocean-current fields and Stokes drift components is bilinear with fill-value.
Contributors other than yourself, if any:
CMEPS Issues Fixed (include github issue #):
#132
Are changes expected to change answers? (specify if bfb, different at roundoff, more substantial)
The updates will change answers for 5 HAFS tests with the WW3 component since a revised mod_def.ww3 is used to include additional output fields.
Any User Interface Changes (namelist or namelist defaults changes)?
No
