+
+! History:     Dec 2016  Module created by Joe Olson and Yi Li.
+!
+! Purpose:     Full 3D representation of the surface stress.
+!
+! References:  Epifanio (2007, MWR)
+!
+! INPUT: U, V, W, vertical eddy viscosity, 
+!        HGT (terrain height), height of first model level, 
+!        map-scale factors 
+!
+! OUPUT: 3D stress (m11,m22,m33,m12,m13,m23)
+!        1D stress (more mesoscale coupling - enhanced u*)

+! Comments:
+! 16-Dec-2016   -  Adding Epifanio's non-local surface velocity calculation
+!                  for serial use only. Need alternative for parallel computing.
