The activities of the CETEMPS Atmospheric Observatory are distributed across two adjacent sites in the mid-mountain region of the Apennine chain: on the outskirts of the city of L’Aquila and in a neighboring rural area. 
Main available instruments: 
Multi-wavelength Raman lidar 
Balloon sounding station 
Ceilometer 
Multiwavelength photometers 
UV pyranometers 
Cloud radar 
Wind lidar 

The specific role of the CETEMPS Atmospheric Observatory mainly concerns the Profiling of aerosols and clouds: 
Optimization of aerosol profiling. 
Improvement of instrumentation, standardization, and quality assessment. 
Exchange of expertise.
