| A micro-pulse lidar system (MPL) which is in Pudong, Shanghai, was used to measure the vertical distribution of aerosols during the period of July 2008 -February 2009. The MPL measurements were made at the top of official building of Pudong Meteorology bureau, and the weather station located on ground beside Shanghai Century Park. The MPL was used to acquire aerosol backscatter, extinction and Aerosol Optical Depth for normal background periods in Shanghai.Aerosol extinction coefficient profiles retrieval methods for lidar are discussed, and an analysis of aerosol optical property acquired in Shanghai is presented. Comparisons of the U.S. Standard Atmosphere and sounding data for retrieval process showed that is good result by using U.S. Standard Atmosphere. The data showed that upslope aerosols appeared during the day and dissipated at night and that the layers were mostly confined to altitudes 3km above ground. Analysis indicate that 84.25% of total aerosol extinction coefficient in the column air (0-6km) contributed by aerosols in 0-2km. Seasonal aerosol extinction coefficient profiles and AODs in Shanghai showed a maximum in summer and a minimum in winter (not including spring).The dominant advantage on continually monitoring aerosol vertical variation of MPL is obvious in one fog & haze weather. It is showed that the top of atmospheric boundary layer was around 1.8 km and it arrived about 2.4 km after noon. Mean while, a high region of aerosol extinction coefficient between 0.6 and 1.2 km occurred after noon.
