NOAA Water (NW) is an airborne, two-channel, closed-path tunable diode laser absorption spectrometer developed by NOAA. It measures water vapor and enhanced total water content in the upper troposphere and lower stratosphere. It was originally designed to fly on NASA’s Global Hawk Uncrewed Aircraft System (UAS), but it can deployed on other high-altitude aircraft. It utilizes second harmonic detection near the 2.7 μm wavelength to measure water vapor. It has a typical sampling frequency of 1 Hz.
