Jalingo vs Kelo

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.

Kelo has more tree cover — 67.5% against 16.6%.

Kelo has cleaner air right now — AQI 22 against 32.

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. Kelo leads here at 67.5%.

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: Jalingo reads 32 (good) and Kelo reads 22 (good) right now.

Frequently asked

Jalingo and Kelo, answered

Which has more trees, Jalingo or Kelo?

Kelo, with roughly 212,058 trees inside its 2 km radius against 52,150. Tree cover tells a slightly different story from raw count: Kelo has the denser canopy at 67.5%.

Which has better air quality, Jalingo or Kelo?

Kelo right now, at AQI 22 against 32 — a gap of 10 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?

Jalingo needs about 42,097 more to reach its canopy target, and Kelo about 0. 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.
