Kecskemét vs Novi Sad

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.

Novi Sad has more tree cover — 21.6% against 17.8%.

Kecskemét has cleaner air right now — AQI 33 against 56.

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. Novi Sad is read from nearby ground stations and Kecskemét 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. Novi Sad leads here at 21.6%.

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: Kecskemét reads 33 (good) and Novi Sad reads 56 (moderate) right now.

Frequently asked

Kecskemét and Novi Sad, answered

Which has more trees, Kecskemét or Novi Sad?

Novi Sad, with roughly 63,651 trees inside its 2 km radius against 55,417. Tree cover tells a slightly different story from raw count: Novi Sad has the denser canopy at 21.6%.

Which has better air quality, Kecskemét or Novi Sad?

Kecskemét right now, at AQI 33 against 56 — a gap of 23 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?

Kecskemét needs about 37,982 more to reach its canopy target, and Novi Sad about 24,753. 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.
