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

Borama vs Hargeysa: your questions answered

Is Hargeysa cleaner than Borama?

On air quality, yes, right now: Hargeysa reads AQI 23 against 35, a gap of 12 points on the US EPA index. This is a live reading rather than an annual average, so it can reverse within a day. Over the past 6 days, on modeled daily averages, Hargeysa averaged AQI 38 against 41, and it was the cleaner of the two on 4 of those days.

Is it safe to exercise outdoors in Borama and Hargeysa today?

The advice is the same for both today. Air quality is satisfactory for everyone. Borama reads AQI 35 and Hargeysa reads AQI 23.

Which has more trees, Borama or Hargeysa?

Hargeysa has more tree cover: 5.4% of the land within 2 km of its center against 1.8% around Borama, or about 16,965 trees against 5,655. Both figures describe the same-sized circle of ground around each center, not the whole municipality.

How many more trees do Borama and Hargeysa need?

Borama needs about 88,593 more to reach its canopy target of 30%, and Hargeysa about 77,283 to reach 30%. The target starts at 30% of the land and rises where air quality is poor.

Are Borama and Hargeysa 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 Borama vs Hargeysa 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.
