By using aerosols as tracers, lidar or laser radar can be applied to study aerosols in the atmosphere that directly or indirectly effect the air quality. The pulsed Nd:YAG lidar system operating at the Ocean Remote Sensing Institute (ORSI), Qingdao, China has been used to get aerosol profiles. The results of the experiments performed on the days with different sky conditions at Qingdao during March-May 2002 indicated significant day-to-day variation in the aerosol profiles. These results are found to be consistent with the aerosol index, which is measured with TOMS (Total Ozone Mapping Spectrometer) and is an index of air quality over a place.
