Reading these numbers
How this comparison is made
Air quality index
The US EPA index, computed from current pollutant concentrations: ground stations where a place has them nearby, and the CAMS atmospheric model everywhere else. It moves hour to hour, so it is a snapshot rather than a verdict on either place. The guideline marks are from the WHO's 2021 air quality guidelines.
Trees and forest
Tree cover is the share of ground under canopy within 2 km of each center, read from Sentinel-2 satellite imagery at 10 m detail. It measures that circle, not the whole municipality, which is what makes the two comparable. Forest loss comes from the University of Maryland's Global Forest Change maps.

Frequently asked
Basrah vs Erbil: your questions answered
Is Basrah cleaner than Erbil?
On air quality, yes, right now: Basrah reads AQI 53 against 57, a gap of 4 points on the US EPA index. This is a live reading rather than an annual average, so it can reverse within a day. But over the past 6 days, on modeled daily averages, Erbil averaged AQI 57 against 152, and it was the cleaner of the two on 6 of those days.
Is it safe to exercise outdoors in Basrah and Erbil today?
The advice is the same for both today. Unusually sensitive people should consider limiting long outdoor exertion. Basrah reads AQI 53 and Erbil reads AQI 57.
Which has more trees, Basrah or Erbil?
Erbil has more tree cover: 5.0% of the land within 2 km of its center against 0.1% around Basrah, or about 15,708 trees against 314. Both figures describe the same-sized circle of ground around each center, not the whole municipality.
How many more trees do Basrah and Erbil need?
Basrah needs about 93,934 more to reach its canopy target of 30%, and Erbil about 78,540 to reach 30%. The target starts at 30% of the land and rises where air quality is poor.
Are Basrah and Erbil measured the same way?
The method is the same: the US EPA index for air, and Sentinel-2 satellite imagery at 10 m detail over an identical radius for trees. Both readings are model estimates, with no ground station close enough to either. Nothing is adjusted for population, city limits or climate.
How often does the Basrah vs Erbil comparison update?
The air readings refresh about once an hour, and each reading's local time is shown at the top of the page. Tree cover comes from the latest clear satellite image of each area (Sep 16, 2026 and Sep 17, 2026), and the forest figures are published yearly.
