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. Logroño leads here at 24.7%.
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: Alcobendas reads 16 (good) and Logroño reads 10 (good) right now.
Frequently asked
Alcobendas and Logroño, answered
Which has more trees, Alcobendas or Logroño?
Logroño, with roughly 77,442 trees inside its 2 km radius against 40,212. Tree cover tells a slightly different story from raw count: Logroño has the denser canopy at 24.7%.
Which has better air quality, Alcobendas or Logroño?
Logroño right now, at AQI 10 against 16 — a gap of 6 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?
Alcobendas needs about 54,035 more to reach its canopy target, and Logroño about 16,617. 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.
