The Raman lidars CONCERNING and MARCO were deployed in Southern France in the frame of the Water Vapor Lidar Network Assimilation-WaLiNeAs experiment. WaLiNeAs is an international field experiment aimed at studying extreme precipitation events and improving their predictability through the assimilation into mesoscale numerical models of water vapour profile measurements from a network of Raman lidar systems. CONCERNING (COmpact RamaN lidar for Atmospheric $CO_2$ and ThERmodyNamic ProfilING) and MARCO (Micropulse Atmospheric Optical Radar for Climate Observations) are two compact and transportable Raman lidar systems designed for long-term all-weather continuous operation, capable to measure high-resolution and accurate $CO_2$ and water vapour mixing ratio profiles, together with temperature and multi-wavelength particle backscatter/extinction/depolarization profiles. CONCERNING was deployed at the Univ. of Toulon (La Garde), with continuous measurements from 29 September 2022 to 25 January 202, while MARCO was deployed in Port-Saint-Louis, with continuous measurements since 19 October 2022. Results from these two systems and from the project will be illustrated at the Congress.
