Water Vapor Sensing System (Winds, Temperatures, and Water Vapor Fields from
Commercial Aircraft) [NCAR/EOL]
https://data.eol.ucar.edu/dataset/51.001

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.
