The atmospheric conditions at cosmic ray observatories, need to be continuously monitored. The measurement of the aerosol profiles, can be accomplished by Raman Lidars (RL). For the AUGER Observatory, we designed a RL that has performed measurements since 2013. The ARCADE RL system, upgraded and tested in L'Aquila, is working at the CTA (Cherenkov Telescope Array) North Observatory since October 2018. In this presentation we report on the performances of these systems, which operate unattended, in terms of the data quality for the assessment of the aerosol contribution to the atmospheric UV optical transparency.
