A system is described which permits the systematic comparing between Lidar reflectivity on the one hand, and aerosol concentration as well as aerological data, on the other hand, taking advantage of the alpine situation high mountain stations, cable cars used as instrument carriers. The Lidar unit is described. Results are discussed using simultaneously obtained Lidar reflectivity profiles and profiles of aerosol concentration condensation nuclei, plus temperature and humidity lapse rates. Very good agreement is found between Lidar reflectivity and logarithm of number of condensation nuclei. With high relative humidities some influence of the growth of the particles is noted which, however, is not sufficient in general to describe Lidar reflectivity profiles.
