Water Vapor Sensing System (2) (WVSS2) Installed and Flying on
Unites Parcel Service (UPS) B-757 Aircraft

Previous flight tests of the WVS22 on the NOAA P-3 yielded high quality upper tropospheric mixing ratio data from this sensor.  Preliminary data from the first UPS B-757 flight tests appear to repeat the data quality shown in the test chamber against the chilled mirror and on NOAA aircraft.

A two week field test is scheduled for late May 2005.  There will be an field test planning meeting in Louisville, KY,  scheduled for the week of March 21st.  Climate's participation is highly encouraged, especially in the data assessment.
