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
Dikhil vs Djibouti: your questions answered
Is Djibouti cleaner than Dikhil?
On air quality, yes, right now: Djibouti reads AQI 36 against 44, a gap of 8 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 7 days, on modeled daily averages, Dikhil averaged AQI 52 against 55, and it was the cleaner of the two on 4 of those days.
Is it safe to exercise outdoors in Dikhil and Djibouti today?
The advice is the same for both today. Air quality is satisfactory for everyone. Dikhil reads AQI 44 and Djibouti reads AQI 36.
Which has more trees, Dikhil or Djibouti?
Djibouti has more tree cover: 2.4% of the land within 2 km of its center against 0.5% around Dikhil, or about 4,901 trees against 1,571. Both figures describe the same-sized circle of ground around each center, not the whole municipality.
How many more trees do Dikhil and Djibouti need?
Dikhil needs about 92,677 more to reach its canopy target of 30%, and Djibouti about 56,360 to reach 30%. The target starts at 30% of the land and rises where air quality is poor.
Are Dikhil and Djibouti 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 Dikhil vs Djibouti 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 18, 2026 and Sep 18, 2026), and the forest figures are published yearly.
