I'm not familiar with the MOM grid_generator program, but the error
message means a call was made to write a value that wouldn't fit into
the specified netCDF variable because of its type.  For example, if
the program tries to store the integer 100000 into a netCDF variable
of type short, you would get this error, because a 16-bit short can't
hold numbers that big.  Similarly, trying to store a large double
value like 1.0e+40 into a float variable would cause this error.
