Field of research

  • In recent years, due to the implementation of a series of emission reduction policies, the fine particulate matter (PM2.5) pollution in the main urban groups in China has been somehow improved. However, the ozone pollution is becoming increasingly serious, which has attracted the attention of the governments and the public. The experience of foreign countries shows that ozone treatment is more difficult than PM2.5, and it takes a long time. The current PM2.5 oriented control strategy adopted in China can not meet the demand of ozone control. After PM2.5 is up to the standard, the air pollution control of the main urban groups in China will surely shift to the focus of ozone control. Taking the near surface ozone pollution in typical photochemical active areas such as Yangtze River Delta and Pearl River Delta as the core, Prof.Yuan focuses on the impact of the air oxidation evolution on the near surface ozone pollution in the following aspects: the emission characteristics of reactive organic matter, the control mechanism of ozone nonlinear change and the influence of the evolution of atmospheric oxidation on the near surface ozone pollution under the background of climate change.

  1. quantification and verification of the source of atmospheric reactive organic matter

  • Reactive organic compounds play an important role in the atmospheric chemical process and ozone generation, but their emission characteristics and chemical transformation have not been fully studied.

  • For the two undeveloped areas in the current reactive organic source research: active component measurement and chemical transformation process correction, the chemical composition spectrum of the important emission sources of reactive organic matter in Yangtze River Region and Pearl River Region was improved with the help of source emission measurement, emission model and literature research. In particular, the missing key active components such as branched chain olefins and reactive aldehydes in the existing reactive organic matter source spectrum were supplemented to build a localized database of reactive organic matter emission sources; After 2016, a list of high spatial-temporal resolution reactive organic matter emission sources in eastern China is constructed. For the important emission sources of reactive organic matter, the chemical transformation process of reactive organic matter in the atmosphere from source to receptor point was quantified. The method of verification of reactive component sources based on ground observation, model inversion and satellite remote sensing was established. The emission trend of reactive organic compounds in Yangtze River Region and Pearl River Region in the next 5-10 years is estimated.

2. study on the control mechanism of ozone nonlinear change in photochemical active area

  • With the help of observation model, 3D air quality model and satellite remote sensing, the relative contribution of local generation and regional transmission to ozone in different regions of Yangtze River Region and Pearl River Region is quantitatively identified, indicating the nonlinear relationship between ozone and its precursors in different regions and their spatial and temporal changes, and the spatial distribution of VOC sensitive areas and NOx sensitive areas, as well as their transition zone under different meteorological conditions are revealed ; The FNR standard for VOC VOC sensitive areas, NOx sensitive areas and their transition zone in Yangtze River Region and Pearl River Region are clarified by using long-term satellite remote sensing data, and the long-term trend of ozone control mechanism is identified. The pattern of dividing sensitive areas of ozone generation is related with NOx and VOCs reduction. This provides scientific basis for controlling the frequency and intensity of ozone pollution events and formulating the medium and long-term ozone standard planning.

 3. the study on the influence of the evolution of atmospheric oxidation on ozone pollution near the ground under the background of climate change

  • Ozone control usually takes decades, and the impact of climate change on ozone pollution on this time scale cannot be ignored. Based on the long-term monitoring results of several stations in Yangtze River Region and Pearl River Region, a conceptual model describing the relationship between ozone, NOx and environmental temperature is established to identify the effect of temperature on the ozone generation efficiency in different regions. The temperature factors are included in the dynamic system of emission source list, and the emission spectrum of some VOCs is sampled and analyzed in different environmental temperature, and the influence of temperature on the emission characteristics of VOCs is clarified; In the localized three-dimensional air quality model, the dynamic emission source list including temperature factors is applied and the environmental temperature is disturbed, the ozone climate compensation effect of the two regions is revealed. The functional relationship between temperature and ozone precursor response is established, which provides scientific basis for the two regions to formulate ozone control strategies under different climate change background.
