Water Vapor Sensing System (WVSS) Data at UCAR/JOSS/NOAA/CODIAC

Abstract: Atmospheric water vapor measurements from commercial aircraft are now
available to complement the real-time winds and temperatures available
from the Aircraft Communication, Addressing and Reporting System
(ACARS). The technology of this first-generation system (WVSS-I) is a
modified Vaisala thin-film sensor. It is considered to be equal to or
better than existing radiosonde humidity data and especially so at the
upper levels of the troposphere. A second-generation system (WVSS-II)
is in progress.
