Baia Mare vs Bălţi
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.
Bălţi has more tree cover — 55.6% against 45.5%.
Bălţi has cleaner air right now — AQI 24 against 28.

What each city is breathing
Concentrations in µg/m³, measured at the same moment as the index above. Lower is better in every row. Both are modelled, with no ground station close enough to either.

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. Bălţi leads here at 55.6%.
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: Baia Mare reads 28 (good) and Bălţi reads 24 (good) right now.
Frequently asked
Baia Mare and Bălţi, answered
Which has more trees, Baia Mare or Bălţi?
Bălţi, with roughly 172,751 trees inside its 2 km radius against 142,942. Tree cover tells a slightly different story from raw count: Bălţi has the denser canopy at 55.6%.
Which has better air quality, Baia Mare or Bălţi?
Bălţi right now, at AQI 24 against 28 — a gap of 4 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?
Baia Mare needs about 0 more to reach its canopy target, and Bălţi 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.
