我们介绍了在澳大利亚新南威尔士州沿海城市伍伦贡进行的城市、海洋和生物空气测量（MUMBA）活动的研究结果。我们将重点放在几个关键的空气质量指标上，并以1公里× 1公里的空间分辨率与区域尺度化学输送模型的预测结果进行比较。我们发现CSIRO化学输运模式在大多数时间提供了臭氧浓度的准确模拟，但低估了极端温度事件期间臭氧增强的发生。该模型还符合先前公布的直径小于2.5微米的细颗粒物（PM2.5）和较大的气溶胶组分（PM10）的性能标准。我们探索了在孟买运动期间观察到的城市空气棚内的大气成分，并讨论了对城市空气质量的不同影响。我们的研究结果表明，通过更准确的人为和生物排放清单以及更好地了解极端温度对空气质量的影响，可以进一步提高我们模拟这个沿海城市空气质量的能力。在伍伦贡城市空气棚内建立空气质量模型所面临的挑战，包括准确模拟当地气象的困难，可能会在南半球的许多其他沿海城市重现。
We present findings from the Measurements of Urban, Marine and Biogenic Air (MUMBA) campaign, which took place in the coastal city of Wollongong in New South Wales, Australia. We focus on a few key air quality indicators, along with a comparison to regional scale chemical transport model predictions at a spatial resolution of 1 km by 1 km. We find that the CSIRO chemical transport model provides accurate simulations of ozone concentrations at most times, but underestimates the ozone enhancements that occur during extreme temperature events. The model also meets previously published performance standards for fine particulate matter less than 2.5 microns in diameter (PM2.5), and the larger aerosol fraction (PM10). We explore the observed composition of the atmosphere within this urban air-shed during the MUMBA campaign and discuss the different influences on air quality in the city. Our findings suggest that further improvements to our ability to simulate air quality in this coastal city can be made through more accurate anthropogenic and biogenic emissions inventories and better understanding of the impact of extreme temperatures on air quality. The challenges in modelling air quality within the urban air-shed of Wollongong, including difficulties in accurate simulation of the local meteorology, are likely to be replicated in many other coastal cities in the Southern Hemisphere.
