It is important to develop a general model to accurately simulate the air pollution in urban street areas. In this paper, the Operational Street Pollution Model (OSPM) initially developed in Denmark is tested with measured data from a relatively wide and open street in Beijing. Major factors influencing the dispersion, such as emission factors, stationary source emissions, and solar radiation, are analyzed. Results show that the model can reflect the basic dispersion pattern in the street but gives systematically higher concentrations. After modifications to estimate street-level wind speed in the model, performance is obviously improved.
开发一个通用模型来准确模拟城市街道区域的空气污染非常重要。本文中，最初在丹麦开发的运行街道污染模型（OSPM）用北京一条相对宽阔且开阔街道的实测数据进行了测试。分析了影响扩散的主要因素，如排放因子、固定源排放和太阳辐射。结果表明，该模型能够反映街道中的基本扩散模式，但系统地给出了更高的浓度值。在对模型中估计街道层面风速的方法进行修改后，性能有了明显改善。
