Abstract

The vertical distributions of ozone (O-3) over a mega city (Beijing, China), and the horizontal O-3 distributions in the lower troposphere (2-3.6 km) over Beijing and its surrounding areas located in the North China Plain (NCP), were analyzed based on the aircraft measurements from 159 flights during 2007-2010. The results are highlighted as follows: (1) There was a peak of O-3 concentration occurring at 1 km over Beijing, and the peak values ranged between 60 and 120 ppbv. (2) There was an O-3 minimum at the surface. The minimum was largely caused by the chemical reaction of NO + O-3. This process produced about 30 ppbv of the O-3 reduction below 0.5 km in the morning (9:00-10:00). (3) There was a transition altitude (similar to 1 km), below which the ozone formation was in a VOC-limited condition, and above which the ozone formation was in a NOx-limited condition. (4) The analysis of the horizontal distribution shows that O-3 concentrations were enhanced in the downwind of the city plumes. This result suggests that there was an important regional O-3 chemical production in the NCP region.
