The Vertical Cavity Surface Emitting Laser (VCSEL) Hygrometer is an airborne hygrometer that measures water vapor concentration in the troposphere and lower stratosphere. It is an open-path, laser-based hygrometer that operates near the 1854 nm wavelength. The VCSEL hygrometer provides real-time water vapor concentration measurements at a sampling rate of 25 Hz. At this rate, the hygrometer has a spatial resolution of approximately 10 meters when the Gulfstream-V aircraft is at maximum speed.
