Description:

Fix a bug in the FV3 write grid component where regional cubed sphere output have undefined (zero) values on some points on the edge (outermost rows and columns). This happens only when model is compiled with -D32BIT=ON option due to round off differences in lat/lon grid coordinate values between forecast and write grid component. When model is compiled without -D32BIT=ON, both forecast and write grid components use 64bit values for grid coordinates and in that case during the remapping all grid points are defined (i.e. 'inside the model domain'). Solution is to use ESMF Redist instead of Remap for all cubed sphere grid outputs.
