Questions about San

What is the tree count in San?

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

The latest reading for San shows an AQI of 58 (Moderate), observed Sep 28, 11:00 local time via Open-Meteo / CAMS, US EPA index. Unusually sensitive people should consider limiting long outdoor exertion.

How is San'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 San; 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.
