CFH
Cryogenic Frost Point Hygrometer

The Cryogenic Frost Point Hygrometer (CFH) is a balloon borne hygrometer developed by the University of Colorado. CFH uses the chilled-mirror principle to measure water vapor from Earth's surface to the mid-stratosphere. It is more sensitive to water vapor compared to standard radiosondes, allowing it to measure dew point temperatures with an accuracy of 0.2 K. CFH collects measurements about every 2 seconds during the balloon’s flight and has a vertical resolution of about 50m in the troposphere to 100m in the stratosphere.
