What each city is breathing
Concentrations in µg/m³, measured at the same moment as the index above. Lower is better in every row. Cluj-Napoca is read from nearby ground stations and Bila Tserkva 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. Bila Tserkva leads here at 48.8%.
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: Bila Tserkva reads 27 (good) and Cluj-Napoca reads 51 (moderate) right now.
Frequently asked
Bila Tserkva and Cluj-Napoca, answered
Which has more trees, Bila Tserkva or Cluj-Napoca?
Bila Tserkva, with roughly 150,090 trees inside its 2 km radius against 112,357. Tree cover tells a slightly different story from raw count: Bila Tserkva has the denser canopy at 48.8%.
Which has better air quality, Bila Tserkva or Cluj-Napoca?
Bila Tserkva right now, at AQI 27 against 51 — a gap of 24 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?
Bila Tserkva needs about 0 more to reach its canopy target, and Cluj-Napoca 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.
