In March 2019, real-time Air Quality information is available for than 11,000 stations in 1000 major cities from 90 countries, thanks to the huge effort from the world EPAs (Environmental Protection Agencies).

There are currently more than 20,000 known air quality monitoring stations in the world, out of which more than 10,000 are published on the World Air Quality Index project. In order to keep a high level on consistency, only stations with particulate matter (PM2.5/PM10) readings are published. The AQI standard for every single published station is based on the US EPA Instant-Cast standard.

The data published on the World Air Quality Index is real-time and therefore unvalidated at the time of publication. However, in order to ensure high level of accuracy for each AQI figures, several machine learning processing solution are used. For instance, data consistency is verified, in real-time, with the neighbor stations, allowing to automatically detect defective monitoring stations, and remove them, if needed, from the map.

The map below shows the location of the known monitoring stations (screen-shot from August 2018):

As the worldwide EPA are continuously developing and increasing the Air Quality monitoring station coverage, this page is regularly updated. For reference, there was 8,000 known stations in September 2014. Below is a non exhaustive list of some of the world-wide EPAs:

關於空氣質量與空氣污染指數

本網站採用的污染指數和顏色與EPA是完全相同的。 EPA的指數可以從 AirNow上查到

空气质量指数 空气质量指数级别（状况）及表示颜色 对健康影响情况 建议采取的措施
0 - 50 一级（优） 空气质量令人满意，基本无空气污染 各类人群可正常活动
51 -100 二级（良） 空气质量可接受，但某些污染物可能对极少数异常敏感人群健康有较弱影响 极少数异常敏感人群应减少户外活动
101-150 三级（轻度污染） 易感人群症状有轻度加剧，健康人群出现刺激症状 儿童、老年人及心脏病、呼吸系统疾病患者应减少长时间、高强度的户外锻炼
151-200 四级（中度污染） 进一步加剧易感人群症状，可能对健康人群心脏、呼吸系统有影响 儿童、老年人及心脏病、呼吸系统疾病患者避免长时间、高强度的户外锻炼，一般人群适量减少户外运动
201-300 五级（重度污染） 心脏病和肺病患者症状显著加剧，运动耐受力降低，健康人群普遍出现症状 儿童、老年人及心脏病、肺病患者应停留在室内，停止户外运动，一般人群减少户外运动
300+ 六级（严重污染） 健康人群运动耐受力降低，有明显强烈症状，提前出现某些疾病 儿童、老年人和病人应停留在室内，避免体力消耗，一般人群避免户外活动
(参考详见 http://zh.wikipedia.org/wiki/空气质量指数)
