The morning sounding today (Friday, June 18,2010) at Tucson exhibits a Td trace that has very little structure through the entire sounding. This kind of simple shape of the moisture profile usually indicates an RH sensor that is not responding to atmospheric conditions. Indeed, a look at the raw data indicates that the RH is stuck at 20% (plus or minus a few percent) for the entire flight. A nasty thing about this kind of bad data is that the PW can be either too great or too low relative to GPS values. In today's case the sounding was a bit too dry wrt the GPS measurement.Friday, June 18, 2010
