Short summary
Chilled mirror hygrometers are the most accurate instruments for measuring water vapor in the upper troposphere and lower stratosphere. The “Golden Points” and nonequilibrium correction are a new post-processing technique for these instruments, which can correct frost point data using mirror reflectance information to achieve unprecedented accuracy of better than 4 % in the H2O mixing ratio, even under rapidly changing humidity conditions, from the ground to the middle stratosphere.
