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. Şabāḩ as Sālim leads here at 4.0%.

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: Şabāḩ as Sālim reads 97 (moderate) and Umm Qaşr reads 96 (moderate) right now.

Frequently asked

Şabāḩ as Sālim and Umm Qaşr, answered

Which has more trees, Şabāḩ as Sālim or Umm Qaşr?

Şabāḩ as Sālim, with roughly 12,566 trees inside its 2 km radius against 3,770. Tree cover tells a slightly different story from raw count: Şabāḩ as Sālim has the denser canopy at 4.0%.

Which has better air quality, Şabāḩ as Sālim or Umm Qaşr?

Umm Qaşr right now, at AQI 96 against 97 — a gap of 1 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?

Şabāḩ as Sālim needs about 81,681 more to reach its canopy target, and Umm Qaşr about 90,478. 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.
