Homyel' vs Ivano-Frankivsk
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.
Homyel' has more tree cover — 53.2% against 43.3%.
Homyel' has cleaner air right now — AQI 33 against 114.

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. Ivano-Frankivsk is read from nearby ground stations and Homyel' 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. Homyel' leads here at 53.2%.
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: Homyel' reads 33 (good) and Ivano-Frankivsk reads 114 (unhealthy for sensitive groups) right now.
Frequently asked
Homyel' and Ivano-Frankivsk, answered
Which has more trees, Homyel' or Ivano-Frankivsk?
Homyel', with roughly 166,966 trees inside its 2 km radius against 133,174. Tree cover tells a slightly different story from raw count: Homyel' has the denser canopy at 53.2%.
Which has better air quality, Homyel' or Ivano-Frankivsk?
Homyel' right now, at AQI 33 against 114 — a gap of 81 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?
Homyel' needs about 0 more to reach its canopy target, and Ivano-Frankivsk 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.
