An innovative rotational Raman lidar to measure the temperature profile from the surface to 30 km altitude

Abstract : The temperature is a fundamental parameter for meteorology and climatology. A concept of innovative rotational Raman lidar with daylight measurement capability is proposed to measure continuously the vertical profile of temperature from the ground to the middle stratosphere. Our goal is to achieve a time resolution permitting the observation of small-scale atmospheric processes playing a role in the troposphere- stratosphere interaction as gravity waves. If successful, this project will open the possibility to consider the Raman rotationnal lidar for weather and climate monitoring from ground, airborne and space applications.
