As Suwayq vs Jebel Ali
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.
As Suwayq has more tree cover — 4.7% against 0.3%.
As Suwayq has cleaner air right now — AQI 91 against 157.

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. Jebel Ali is read from nearby ground stations and As Suwayq 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. As Suwayq leads here at 4.7%.
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: As Suwayq reads 91 (moderate) and Jebel Ali reads 157 (unhealthy) right now.
Frequently asked
As Suwayq and Jebel Ali, answered
Which has more trees, As Suwayq or Jebel Ali?
As Suwayq, with roughly 8,446 trees inside its 2 km radius against 942. Tree cover tells a slightly different story from raw count: As Suwayq has the denser canopy at 4.7%.
Which has better air quality, As Suwayq or Jebel Ali?
As Suwayq right now, at AQI 91 against 157 — a gap of 66 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?
As Suwayq needs about 45,464 more to reach its canopy target, and Jebel Ali about 124,721. 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.
