ESRL/GMD Water Vapor
The water vapor group at NOAA/ESRL/GMD has been measuring water vapor
in the upper troposphere and lower stratosphere since 1980 using small balloon
borne frost-point hygrometers. These hygrometers are built and calibrated in
our laboratory. The focus of our research is long term monitoring of stratospheric
water vapor and the processes that control stratospheric and upper tropospheric
water vapor. Aside from our long term monitoring program at Boulder, we have
conducted several intensive programs in Antarctica, the Arctic, and several
equatorial locations.
Currently, we are involved in the Observations of the Middle Stratosphere (OMS)
research project as well as the Soundings of Ozone and Water Vapor in Equatorial
Regions (SOWER) mission.
