Citizens' Data for Air Pollution (CitiDAir)

空气污染已成为当今的环境危机之一。现在有一个消费空气监测仪的市场，这使得公众比以前更容易获得污染监测。消费者监测器与研究人员使用的污染监测器在成本（这些监测器可能比研究仪器便宜许多倍）、用户友好性和质量（这些监测器的长期可靠性和准确性存在很大的不确定性）方面有所不同。由于现有的国家空气污染监测站相对较少，因此经常使用数学模型来填补缺失的数据。然而，模型仍然需要来自监测器的地面校准，因此仍然需要跨空间和时间进行更高分辨率的监测，以改进模型估计。建立高分辨率监测网的成本仍然过高。移动监控是获得这种高分辨率数据的另一种潜在方式。市民可以成为移动监测的一种形式，我们将探索发展一项运动的可行性，让市民作为数据收集者，跨时间和空间测量空气污染。我们还将探索使用消费者空气监测仪的可能性，以确定这项工作是否可以由公民主导，而不是依靠研究人员提供监测设备。我们还将探讨人们如何与数据收集过程和他们收集的数据互动，以及他们从这项活动中获得的好处，以便更好地将公民科学纳入未来的空气污染暴露研究。

Air pollution has figured prominently as one of the environmental crises of the day. There is now a market in consumer air monitors, which makes pollution monitoring more accessible to the public than before. Consumer monitors are distinguished from the pollution monitors used by researchers in terms of cost (these can be many times cheaper than research instruments), user friendliness, and quality (there is great uncertainty about the long-term reliability and accuracy of these monitors). Because of the existing national monitoring stations for air pollution are relatively few, mathematical models are often used to fill in missing data. However, models still require ground-level calibration from monitors, so there is still a need for higher resolution monitoring across space and time for improving model estimates. Establishment of a high resolution monitoring network is still cost-prohibitive. Mobile monitoring is another potential way of obtaining this high resolution data. Citizens could be a form of mobile monitoring, and we will explore the feasibility of developing a campaign to measure air pollution across time and space with citizens as data collectors. We will also explore the possibility of using consumer air monitors to determine whether this effort could be citizen-led, rather than relying on researchers to supply monitoring equipment. We will also explore how people interact with the data collection process and the data they collect, as well as the benefits they receive from this activity, to better incorporate citizen science into future air pollution exposure research.
