Questions about Macau

What is the tree count in Macau?

Macau has an estimated 38,128 trees across the 9.84 km² of land measured — 15.5% tree cover, 14 percentage points short of the 30% tree-cover target set for this area.

How many more trees does Macau need?

What is the air quality (AQI) in Macau right now?

The latest reading for Macau shows an AQI of 67 (Moderate), observed Sep 28, 14:00 local time via Open-Meteo / CAMS, US EPA index. Unusually sensitive people should consider limiting long outdoor exertion.

How is Macau's tree cover and air quality measured?

Tree cover is measured from Sentinel-2 L2A (ESA Copernicus) via Earth Search satellite imagery at 10 m detail across a 2 km radius around St. Anthony's Parish; the tree count is an estimate derived from that cover. Air quality comes from ground monitoring stations via OpenAQ where one reports nearby, and otherwise, as here, from the Open-Meteo / CAMS model, which may differ from street-level monitors.
