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. Tanta leads here at 4.5%.

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: Al ‘Āshir min Ramaḑān reads 60 (moderate) and Tanta reads 33 (good) right now.

Frequently asked

Al ‘Āshir min Ramaḑān and Tanta, answered

Which has more trees, Al ‘Āshir min Ramaḑān or Tanta?

Tanta, with roughly 14,137 trees inside its 2 km radius against 8,168. Tree cover tells a slightly different story from raw count: Tanta has the denser canopy at 4.5%.

Which has better air quality, Al ‘Āshir min Ramaḑān or Tanta?

Tanta right now, at AQI 33 against 60 — a gap of 27 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?

Al ‘Āshir min Ramaḑān needs about 86,080 more to reach its canopy target, and Tanta about 80,111. 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.
