The Leipzig Aerosol and Clouds Remote Observations System (LACROS) is a combined aerosol and cloud remote-sensing mobile facility. It consists of cloud radar, Raman and Doppler lidars, and additional instruments for passive and active remote sensing. The co-located, continuous observations enable the development and application of sophisticated retrieval algorithms by exploiting instrument synergies.

The large number of unsolved questions concerning the interaction between aerosol particles and clouds and corresponding indirect effects on precipitation and radiative transfer demand new measurement strategies to resolve the atmospheric processes involved. In this regard, obtaining synergistic information about cloud and aerosol properties from multi–instrument and hence multi–sensor observations is a key approach to overcome the current lack of knowledge. Motivated by these needs, the mobile multi–instrument exploratory platform LACROS is being operated by the Department of Remote Sensing of Atmospheric Processes at TROPOS.
