The CETEMPS Atmospheric Observatory is active in lidar sounding of the atmosphere since late ’80: from tropospheric measurements of the aerosol optical properties and water vapor mixing ratio, to the observations of the stratospheric ozone concentration and aerosol backscatter.

The CETEMPS Atmospheric Observatory has been involved in several international projects and experiments.
Particular efforts have been devoted to the quality assurance of the observational data testing the performances of the retrieval algorithms and of the system hardware.

The CETEMPS Atmospheric Observatory instrumentation includes:

• multi-wavelength Raman Lidar (ACTRIS-EARLINET) for the retrieval of the optical properties of aerosols and of water vapor mixing ratio. A database of measurements spanning about 15 years is available;
• balloon radiosounding station for the measurement of the temperature, pressure, relative humidity and ozone profiles. More than 275 profiles have been recorded in the last twenty years;
• sun photometer (AERONET) for the automatic and continuous measurements of the daytime aerosol columnar optical properties. This instrument is in operation since 2014;
• radiometers measuring UV-A and UV-B solar irradiance at ground;
• meteorological ground station;
• polarimetric X-band Weather Radar.

The CETEMPS Atmospheric Observatory is responsible of Raman Lidar systems measuring the aerosol optical depth vertical profile in high energy cosmic ray experiments (the AUGER Observatory in Malargue, Argentina, and the Cherenkov Telescope Array in La Palma, Spain).
