ClearfLo: Clean Air for London

糟糕的空气质量，特别是在城市地区，对人类健康有明显的影响，但负责产生主要污染物的过程，即颗粒物、臭氧、二氧化氮和热量，还没有得到很好的了解和预测。ClearfLo的目标是提供伦敦城市大气的气象、成分和颗粒物含量的综合测量，在街道水平和高架地点进行测量，并辅之以建模，以提高对空气质量的预测能力。为实现这一雄心，将在伦敦建立新的测量能力，用于长期测量和密集观察期，并对测量进行分析和建模，以建立关键过程。

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.
