Beijing Air Quality during the Olympics
This map shows daily updated air quality around Beijing, China and the Olympics Venues from GeoCommons Finder!
The API or air pollution index indicates air quality for SO2, NO2, and PM10 (particulate matter that is 10 micrometers in diameter or less). The USA and Canada both use AQI, air quality index, which is similar to API but the indices are set according to different formulas based upon concentration. Therefore, one cannot compare API or AQI between countries without knowing what concentration is represented by the indices.
API Rating (Beijing)
0-50 Grade I (Excellent)
51-100 Grade II (Good)
101-200 Grade III (Lightly Polluted)
201-300 Grade IV (Moderately Polluted)
300+ Grade V (Seriously Polluted)
