随着 COVID-19 在世界各地蔓延，世界空气质量指数项目团队发现对覆盖整个世界地图的全球数据的请求激增。因此，WAQI 项目现在提供了一个新的专用数据集，从 2015 年 1 月至今，每天更新 3 次，覆盖全球约 380 个主要城市。
每个主要城市的数据都是基于几个站点的平均值（中位数）。该数据集提供每种空气污染物种类（PM2.5、PM10、臭氧...）的最小值、最大值、中值和标准差以及气象数据（风、温度……）。
所有空气污染物种类均转换为美国 EPA 标准（即无原始浓度）。所有日期均基于 UTC。
计数列是用于计算中位数和标准差的样本数。
城市中值是使用可用气象站的所有 AQI 值每天计算的
2015年至今的数据集：
如果您使用此数据集从研究中获得任何结果，请通过数据平台请求表向我们发送消息，并附上您的研究结果或文章的链接，让我们知道。我们将编制一份所有基于 COVID-19 空气质量的研究的列表，并创建一个新页面供所有人查看。
