Boa Vista vs Manaus
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.
Manaus has more tree cover — 23.2% against 15.5%.
Boa Vista has cleaner air right now — AQI 29 against 77.

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. Manaus is read from nearby ground stations and Boa Vista is modelled — worth knowing, since the two are not quite like for like.
PM2.5
Fine particles, the pollutant that usually sets the index.

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. Manaus leads here at 23.2%.
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: Boa Vista reads 29 (good) and Manaus reads 77 (moderate) right now.
Frequently asked
Boa Vista and Manaus, answered
Which has more trees, Boa Vista or Manaus?
Manaus, with roughly 72,885 trees inside its 2 km radius against 42,754. Tree cover tells a slightly different story from raw count: Manaus has the denser canopy at 23.2%.
Which has better air quality, Boa Vista or Manaus?
Boa Vista right now, at AQI 29 against 77 — a gap of 48 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?
Boa Vista needs about 39,996 more to reach its canopy target, and Manaus about 21,363. 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.
