This merge corrects an error in deriving the water vapor mixing ratio field (QV) from
relative humidity (RH) for real-data cases.
Under the assumption that real-data intermediate files were produced by the WPS's
ungrib program, we should always assume that the RH field is with respect to liquid water,
since this is what WRF's real.exe program assumes and what the WPS ungrib.exe produces.
Thanks to The Weather Company for uncovering this issue.
