ClearfLo: Clean Air for London

空气质量差，特别是在城市地区，对人类健康有明显的影响，但产生主要污染物，即微粒物质、臭氧、二氧化氮和热量的过程没有得到很好的了解，也没有得到很好的预测。ClearfLo的目标是提供伦敦城市大气的气象学、成分和颗粒负荷的综合测量，在街道和高架地点进行测量，并辅以建模，以提高空气质量的预测能力。这一目标将通过在伦敦建立新的测量能力来实现，这些能力将用于长期测量和密集观察期，并通过分析和模拟测量来建立关键过程。

Poor air quality, particularly in urban areas, has a demonstrable effect on human health, but the processes responsible for producing the main pollutants, namely particulate matter, ozone, nitrogen dioxide and heat are not well understood and are poorly predicted. The ambition of ClearfLo is to provide integrated measurements of the meteorology, composition and particulate loading of London's urban atmosphere, made at street level and at elevated sites, complemented by modelling, to improve predictive capability for air quality. This ambition will be addressed by establishing new measurement capabilities in London, which will be used for long-term measurements and intensive observation periods, and by analysis and modelling of the measurements to establish key processes.
