U.S. Mission India NowCast Air Quality Index
The U.S. Embassy and Consulates’ air quality monitors measure airborne fine particulate matter (commonly referred to as PM 2.5 because they are less than or equal to 2.5 microns in diameter) on the compounds of the Embassy and Consulates. Data from a single monitoring station cannot be applied to an entire city. Therefore, air quality data collected at the U.S. Embassy and Consulates may differ from other monitors located in the same cities.
