CIAO is one of the most advanced infrastructures for ground based remote sensing in Europe equipped by multi-wavelength lidar and scanning cloud radar plus additional operative instruments and is providing since early 2000s high quality long term observations of aerosol and cloud properties .
Currently, CIAO is enlarging the equipment with more advanced state of the art lidar systems, and instruments for aerosol in situ and clouds and trace gases remote sensing measurements. Additionally, an ICOS Atmosphere Class1 station is under implementation at CIAO complementing aerosol clouds and trace gases observations with carbon cycle relevant ones.
