LiCal is the official Lidar Calibration Centre for the Aerosol, Clouds and Trace gases Research Infrastructure (ACTRIS). LiCal is now open to weather services and aviation safety administrations, lidar/ceilometer developers, as well as to new lidar stations within the research community.

The various installations of LiCal have offered in the last years a significant number of accesses within EARLINET, ACTRIS, ESA-CEOS, ITaRS, as well as for the master and doctoral programs at the Romanian, Italian and German Universities, and national research programs.
