Short summary

This paper describes the fidelity of vertical profile measurements of atmospheric water vapor using the Cryogenic Frostpoint Hygrometer (CFH), which depends on the stability of the calibration, instrument behaviour, and validation of these measurements with respect to a reference. Being able to characterize each of these elements is essential in the understanding long time series of atmospheric water vapor measurements and in the interpretation of water vapor process studies.
