Ashkelon vs East Jerusalem
Tree cover and air quality for both, measured the same way: Sentinel-2 imagery at 10 m detail over a 2 km radius from each city centre, and the live US EPA air quality index. Same radius and same index, so the two numbers compare directly.
Ashkelon has more tree cover — 10.3% against 4.6%.
East Jerusalem has cleaner air right now — AQI 51 against 53.

Air quality in detail
What each city is breathing
Concentrations in µg/m³, measured at the same moment as the index above. Lower is better in every row. Ashkelon is read from nearby ground stations and East Jerusalem is modelled — worth knowing, since the two are not quite like for like.

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. Ashkelon leads here at 10.3%.
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: Ashkelon reads 53 (moderate) and East Jerusalem reads 51 (moderate) right now.
Frequently asked
Ashkelon and East Jerusalem, answered
Which has more trees, Ashkelon or East Jerusalem?
Ashkelon, with roughly 32,294 trees inside its 2 km radius against 14,451. Tree cover tells a slightly different story from raw count: Ashkelon has the denser canopy at 10.3%.
Which has better air quality, Ashkelon or East Jerusalem?
East Jerusalem right now, at AQI 51 against 53 — a gap of 2 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?
Ashkelon needs about 61,766 more to reach its canopy target, and East Jerusalem about 79,796. 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.
