For monitoring the water vapor content in the polar troposphere and stratosphere a Lyman-α/OH fluorescence hygrometer is very useful owing to its rapid response, high sensitivity and wide dynamic range. Cooperative measurement of Lα/OH fluorescence hygrometry with other monitoring techniques of atmospheric water vapor such as satellite, Raman scattering lidar, balloon-borne carbon humidity sensor and so on will produce abundant results which help understand the water vapor concentration in the polar atmosphere.
