What each city is breathing
Concentrations in µg/m³, measured at the same moment as the index above. Lower is better in every row. Ras Al Khaimah is read from nearby ground stations and Al Ain City 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. Ras Al Khaimah leads here at 21.8%.
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: Al Ain City reads 118 (unhealthy for sensitive groups) and Ras Al Khaimah reads 173 (unhealthy) right now.
Frequently asked
Al Ain City and Ras Al Khaimah, answered
Which has more trees, Al Ain City or Ras Al Khaimah?
Ras Al Khaimah, with roughly 39,859 trees inside its 2 km radius against 7,226. Tree cover tells a slightly different story from raw count: Ras Al Khaimah has the denser canopy at 21.8%.
Which has better air quality, Al Ain City or Ras Al Khaimah?
Al Ain City right now, at AQI 118 against 173 — a gap of 55 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?
Al Ain City needs about 102,730 more to reach its canopy target, and Ras Al Khaimah about 33,277. 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.
