The Uncrewed Aerial System (UAS) Laser Hygrometer (ULH) is an in situ airborne hygrometer developed at the Jet Propulsion Laboratory (JPL). It was designed to measure water vapor in the upper troposphere and lower stratosphere on UAS. It uses a continuous laser (1370 nm) beam and two mirrors to detect the water vapor concentration around the aircraft. ULH can provide data rates up to 20 Hz, allowing for a spatial resolution of 10 meters or less. It has a detection limit of less than 1 ppmv.
