How does Airleaf measure air quality in Tonga?
Each city's reading is the US EPA air quality index, from ground monitoring stations where one has reported recently nearby, and from the CAMS atmospheric model elsewhere; each city's report says which. Tree cover is measured over the same 2 km radius in every city, so the cities compare like for like.
