项目摘要

CityScan - a revolution in air quality monitoring. Poor air quality has a number of proven links with poor health and shortened life-expectancy. Each city council within the United Kingdom has an obligation to measure and report on air quality to national government. The UK government in turn is required to meet targets set out in European Union directives. Similar requirements exist throughout the world, in addition to requirements for emission monitoring in certain industrial and commercial environments as well as measurements needed for scientific research. CityScan uses scattered sunlight to measure the concentration and distribution of certain air pollutants over city centres and other areas of interest. Using just two ground stations, the distribution of gases such as nitrogen dioxide can be measured over areas up to 100 square kilometers. This provides information on major emission sources, and the subsequent distribution of these gases over surrounding areas. This is key information for local councils who are required to monitor emissions within urban environments and manage air quality for the benefit of residents and workers. The technology used to retrieve all this information is under development at the University of Leicester's space research centre. Techniques used in satellite instruments are being deployed on roof-tops to provide an unprecidented level of information on air quality for the benefit of city councils, scientists and local residents.

城市扫描--空气质量监测领域的一场革命。糟糕的空气质量已被证明与健康状况不佳和预期寿命缩短有关。英国的每个市议会都有义务测量空气质量并向国家政府报告。反过来，英国政府又被要求达到欧盟指令中设定的目标。除了对某些工商业环境中的排放监测以及科学研究所需的测量的要求外，世界各地都有类似的要求。CityScan使用散射的阳光来测量某些空气污染物在市中心和其他感兴趣的地区的浓度和分布。只需使用两个地面站，就可以在100平方公里的区域内测量二氧化氮等气体的分布。它提供了主要排放源的信息，以及这些气体随后在周围地区的分布情况。这是地方议会的关键信息，地方议会被要求监测城市环境中的排放，并为居民和工人的利益管理空气质量。莱斯特大学太空研究中心正在开发用于检索所有这些信息的技术。卫星仪器中使用的技术正被部署在屋顶上，为市议会、科学家和当地居民提供无价的空气质量信息。
