Water Vapor Sensing System (Winds, Temperatures, and Water Vapor Fields from Commercial Aircraft) [NCAR/EOL]
Summary
This data set contains the JOSS quality controlled WVSS-I data. This data has consistent water vapor information (dewpoint, RH, and mixing ratio are consistent), and has the benefit of time continuity to check for changes in WVSS-I calibration. IMPORTANT NOTE: The sensor technology of the first generation Water Vapor Sensing System (WVSS-I) is Vaisala's thin-film capacitor. Though a better sensor than found on radiosondes, it still loses calibration over time. The data from WVSS-I gathered from July 1, 1999 to December 31, 1999 has been evaluated and a scientific article is being prepared. This data is useful with data from four of the six aircraft considered quite good. One aircraft (#376) appears approximately 5% too wet and one aircraft (#441) appears approximately 5% too dry (very dry in November and December 1999). See the README for further information.
