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. Nāḩiyat al Iskandarīyah leads here at 6.0%.
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: Abū Ghurayb reads 102 (unhealthy for sensitive groups) and Nāḩiyat al Iskandarīyah reads 114 (unhealthy for sensitive groups) right now.
Frequently asked
Abū Ghurayb and Nāḩiyat al Iskandarīyah, answered
Which has more trees, Abū Ghurayb or Nāḩiyat al Iskandarīyah?
Nāḩiyat al Iskandarīyah, with roughly 18,774 trees inside its 2 km radius against 16,965. Tree cover tells a slightly different story from raw count: Nāḩiyat al Iskandarīyah has the denser canopy at 6.0%.
Which has better air quality, Abū Ghurayb or Nāḩiyat al Iskandarīyah?
Abū Ghurayb right now, at AQI 102 against 114 — a gap of 12 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?
Abū Ghurayb needs about 92,991 more to reach its canopy target, and Nāḩiyat al Iskandarīyah about 90,742. 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.
