Short summary
The two-channel NOAA Water instrument was developed for in situ measurement of water vapor and cirrus cloud ice water content (IWC) in the upper troposphere and lower stratosphere. Tunable diode laser absorption is used to achieve accurate measurements at part per million H2O and low µg/m3 IWC. This paper reports the instrument’s design and performance achieved during its first aircraft deployment on the NASA Global Hawk during the 2013 ATTREX mission in the tropical tropopause layer.
