Air Quality by Country: Median PM2.5 and PM10 from Citizen Sensors (Sensor.Community)

sensorcommunityluftdaten/particulate-by-country

A worldwide snapshot of fine-dust readings from the Sensor.Community citizen sensor network, reduced to one row per country: the number of outdoor sensors and the median PM2.5 and PM10 in micrograms per cubic metre, most sensors first, with the timestamp of the newest reading (UTC). Built from the network's dust feed, which holds each sensor's average over the last 5 minutes; indoor sensors and readings outside 0 to 1000 are left out. Takes no input. These are low-cost citizen sensors, not reference-grade monitors. Served by Eden Engine; not an official Sensor.Community product.
