What each city is breathing
Concentrations in µg/m³, measured at the same moment as the index above. Lower is better in every row. Sonārgaon is read from nearby ground stations and Brāhmanbāria 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. Sonārgaon leads here at 82.0%.
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: Brāhmanbāria reads 151 (unhealthy) and Sonārgaon reads 149 (unhealthy for sensitive groups) right now.
Frequently asked
Brāhmanbāria and Sonārgaon, answered
Which has more trees, Brāhmanbāria or Sonārgaon?
Sonārgaon, with roughly 195,526 trees inside its 2 km radius against 101,136. Tree cover tells a slightly different story from raw count: Sonārgaon has the denser canopy at 82.0%.
Which has better air quality, Brāhmanbāria or Sonārgaon?
Sonārgaon right now, at AQI 149 against 151 — a gap of 2 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?
Brāhmanbāria needs about 1,280 more to reach its canopy target, and Sonārgaon 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.
