What each city is breathing
Concentrations in µg/m³, measured at the same moment as the index above. Lower is better in every row. Al-'Ubūr is read from nearby ground stations and Al Ḩawāmidīyah 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. Al Ḩawāmidīyah leads here at 40.9%.
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 Ḩawāmidīyah reads 58 (moderate) and Al-'Ubūr reads 164 (unhealthy) right now.
Frequently asked
Al Ḩawāmidīyah and Al-'Ubūr, answered
Which has more trees, Al Ḩawāmidīyah or Al-'Ubūr?
Al Ḩawāmidīyah, with roughly 128,491 trees inside its 2 km radius against 21,991. Tree cover tells a slightly different story from raw count: Al Ḩawāmidīyah has the denser canopy at 40.9%.
Which has better air quality, Al Ḩawāmidīyah or Al-'Ubūr?
Al Ḩawāmidīyah right now, at AQI 58 against 164 — a gap of 106 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 Ḩawāmidīyah needs about 0 more to reach its canopy target, and Al-'Ubūr about 103,673. 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.
