Short description (English)	The first objective of this project is the implementation of an operational water vapor and aerosol LIDAR system at MeteoSwiss. The MeteoSwiss-LIDAR will supply data with high spatial and temporal resolution, thus helping to improve the database for direct meteorological applications by adding real time water vapor and aerosol backscatter profiling. It will provide MeteoSwiss and EPFL with a database of great importance for climate change modelling and trend analysis in aerosol and water vapor content in the troposphere. The second objective is the application of the LIDAR information together with conventional data for comparison, validation and further development of the prognostic model aLMo. The resulting “combined Swiss Alpine site” (Payerne, Arosa and Jungfraujoch), will enable MeteoSwiss to fulfil the requirements defined in the Global Water Vapor Project (GVaP) of WMO-GEWEX for a level-1 reference station.
