Compare cities and countries: tree cover and air quality

A single city's tree cover only means something next to another one. Everything here was measured the same way — Sentinel-2 imagery at 10 m detail over a 2 km radius, and the live US EPA air quality index — so any two places can be read against each other directly. Compare two cities, or two countries by the average across every city measured in each.
