许多国家使用基于网格的数值空气扩散模型（通常称为“区域”模型）进行国家空气质量评估。这些模型的优点包括能够使用时空变化的气象学并在大时空尺度上模拟化学反应。这些模型通常在农村和城市背景监测中表现相当好，但路边监测的预测被低估。城市尺度的空气扩散模型已被开发出来以提供高空间分辨率，但通常仅限于使用空间均匀的气象数据并在短时间尺度上模拟简化的化学反应。因此，区域和城市规模的空气扩散模型具有互补的优势，并且将城市规模模型嵌套在区域模型中的系统允许在一系列空间尺度上进行准确的空气扩散建模。本文介绍了本地模型 ADMS-Urban 嵌套在区域模型 CMAQ 中的系统的初步建模结果。
Many countries perform national air quality assessments using grid-based numerical air dispersion models, generally referred to as ‘regional’ models. Advantages of these models include the ability to use temporally and spatially varying meteorology and model chemical reactions over large temporal and spatial scales. These models usually perform reasonably well against rural and urban background monitors, but predictions at roadside monitors are underestimated. City-scale air dispersion models have been developed to give high spatial resolution, but are usually restricted to use spatially homogeneous meteorological data and to model simplified chemical reactions over short time scales. Thus, regional and city-scale air dispersion models have complementary strengths and a system where a city-scale model is nested within a regional model allows accurate air dispersion modelling over a range of spatial scales. This paper presents preliminary modelling results from a system where the local model ADMS-Urban is nested within the regional model, CMAQ.
