Abstract Spatial and temporal characteristic of aerosol in Beijing were analyzed based on 12-year (2007 to 2018) aerosol observation data through aircraft Yun-12 and King Air. It denoted that the aerosol number concentration in early years has a significant negative growth trend, while the effective diameter has a positive trend. The seasonal variation of aerosol vertical profile was closely related to the seasonal meteorology variation and seasonal PBL variation. The vertical profiles of aerosols in each season or under different weather system were affected by PBL height. The aerosols mixed adequately under PBL height. However, the number concentration near ground in summer is lower than that in winter. It was because higher PBL height in summer allows pollutant mixed evenly in a large vertical extent. The vertical variation of scattering coefficients on 550nm was in good agreement with the aerosol number concentration. High values were usually found in polluted days and winter.
