Instrument

FPH
Frost Point Hygrometer

The NOAA Frost Point Hygrometer (FPH) is a balloon-borne sensor that collects profile measurements of atmospheric water vapor. It uses the chilled-mirror principle to measure the frost or dew point temperature up to 28 km in the atmosphere. FPH takes measurements at a vertical resolution of 5-10 m and a temporal resolution of 1-2 seconds.
