Another attempt at looking at the NUCAPs sounding and comparing to a local METAR and RTMA. This time the modified soundings seemed to do much better. The NUCAPs sounding point was roughly 2 miles away from the BMT METAR which was measuring a temp/dew of 81/73. RTMA was measuring 80/74 at the NUCAPs sounding location. NUCAPs unmodified sounding came in at 74/69 (not shown), however, the modified sounding was adjusted to 78/71.

So the modified sounding was adjusted well from the original, but looks like it may have not been adjusted far enough for this case. Although if there’s a bias throughout the sounding perhaps correcting too far would make the sounding unrealistic. Not sure w/o in situ observations throughout the troposphere.
