This study investigates the potential usefulness of a commercial laser ceilometer, an instrument used operationally at most airports for monitoring cloud base, for providing an inexpensive, continuous indication of air quality. Using lidar principles, a method is presented in which the ceilometer can provide information on the aerosol optical properties of the atmosphere. Further insight into the ceilometer measurements is obtained by comparing observations with aircraft, lidar, and a RASS-equipped profiler. The results of this work show that the ceilometer can provide estimates of aerosol extinction in the lower troposphere under sufficiently hazy conditions.
