Aix-en-Provence vs Parma
Tree cover and air quality for both, measured the same way: Sentinel-2 imagery at 10 m detail over a 2 km radius from each city centre, and the live US EPA air quality index. Same radius and same index, so the two numbers compare directly.
Aix-en-Provence has more tree cover — 42.2% against 32.1%.
Parma has cleaner air right now — AQI 10 against 24.

Reading these numbers
What is actually being measured
Tree cover
The share of ground under canopy inside a 2 km radius of each city centre, read from Sentinel-2 satellite imagery at 10 m detail. It is a measurement of that circle, not of the whole municipality — which is exactly what makes the two comparable, since city boundaries are drawn to wildly different rules around the world. Aix-en-Provence leads here at 42.2%.
Air quality index
The live US EPA index, computed from current pollutant concentrations — ground stations where a city has them nearby, and a model everywhere else. It moves hour to hour, so this is a snapshot rather than a verdict on either place: Aix-en-Provence reads 24 (good) and Parma reads 10 (good) right now.
Frequently asked
Aix-en-Provence and Parma, answered
Which has more trees, Aix-en-Provence or Parma?
Aix-en-Provence, with roughly 132,575 trees inside its 2 km radius against 100,845. Tree cover tells a slightly different story from raw count: Aix-en-Provence has the denser canopy at 42.2%.
Which has better air quality, Aix-en-Provence or Parma?
Parma right now, at AQI 10 against 24 — a gap of 14 points. This is a live reading rather than an annual average, so it can reverse within a day.
How many more trees does each city need?
Aix-en-Provence needs about 0 more to reach its canopy target, and Parma about 0. The target is the same share of ground for both, so the figures are directly comparable.
Are these two measured the same way?
Yes — that is the point of the page. Identical radius, identical satellite source at 10 m detail, and the same US EPA index for air. Nothing here is adjusted for population, city limits or climate, so the numbers describe the same-sized circle of ground in each place.
