The NOAA Water instrument is a two-channel, closed-path, tunable diode laser absorption spectrometer developed to measure both water vapor and enhanced total water content (sum of water vapor and inertially enhanced condensed phase) in the upper troposphere and lower stratosphere. It was originally designed to fly on the NASA Global Hawk Unmanned Aerial Vehicle, but it can fly on any high-altitude aircraft. The detection cells within the instrument are operated at a constant temperature, pressure, and flow conditions to maintain a constant sensitivity to ingested water regardless of the environment that is being sampled. Calibration of the instrument can also be completed periodically on-board to ensure the instrument remains stable during flight.
