Airborne Weather LiDAR

Zhien Wang, a professor in the UW Department of Atmospheric Science, and Perry Wechsler, a UW senior research scientist and chief engineer of the King Air, recently received a $1.2 million National Science Foundation (NSF) grant to develop a Multi-function Airborne Raman Lidar (MARLi). The Raman Lidar will simultaneously measure profiles of temperature, water vapor mixing ratio, clouds and aerosol. Lidar, an acronym for light detection and ranging, is an optic remote sensing technology that can be used to detect and measure molecular aerosols and cloud droplets in the atmosphere.

Raman scattering or the Raman effect is the inelastic scattering of a photon. Raman lidar is used in atmospheric physics to measure the atmospheric extinction coefficient and the water vapour vertical distribution.
