Pump-probe differential Lidar to quantify atmospheric supersaturation and particle-forming trace gases

Abstract

We propose a pump-probe differential Lidar technique to remotely map the ability of the atmosphere to undergo particle condensation, which depends on the concentration of both pre-existing nanoparticles and condensable species or their precursors. Besides its interest for improving short-time, local weather forecast, this technique could provide information on atmospheric parameters such as the concentration of condensable species and physical parameters including the temperature and relative humidity.
