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. Originally designed for installation on NASA’s Global Hawk Uncrewed Aircraft System (UAS), it can also be deployed on other high-altitude aircraft. It uses second harmonic detection near the 2.7 μm wavelength to measure water vapor. Its typical sampling frequency is 1 Hz.
