Asunción vs Maringá
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.
Maringá has more tree cover — 32.0% against 20.9%.
Maringá has cleaner air right now — AQI 43 against 86.

Air quality in detail
What each city is breathing
Concentrations in µg/m³, measured at the same moment as the index above. Lower is better in every row. Asunción is read from nearby ground stations and Maringá is modelled — worth knowing, since the two are not quite like for like.

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. Maringá leads here at 32.0%.
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: Asunción reads 86 (moderate) and Maringá reads 43 (good) right now.
Frequently asked
Asunción and Maringá, answered
Which has more trees, Asunción or Maringá?
Maringá, with roughly 100,430 trees inside its 2 km radius against 57,452. Tree cover tells a slightly different story from raw count: Maringá has the denser canopy at 32.0%.
Which has better air quality, Asunción or Maringá?
Maringá right now, at AQI 43 against 86 — a gap of 43 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?
Asunción needs about 25,015 more to reach its canopy target, and Maringá 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.
