Ajmer vs Jhānsi
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.
Ajmer has more tree cover — 43.0% against 29.6%.
Jhānsi has cleaner air right now — AQI 67 against 70.

What each city is breathing
Concentrations in µg/m³, measured at the same moment as the index above. Lower is better in every row. Both are modelled, with no ground station close enough to either.

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. Ajmer leads here at 43.0%.
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: Ajmer reads 70 (moderate) and Jhānsi reads 67 (moderate) right now.
Frequently asked
Ajmer and Jhānsi, answered
Which has more trees, Ajmer or Jhānsi?
Ajmer, with roughly 135,088 trees inside its 2 km radius against 92,340. Tree cover tells a slightly different story from raw count: Ajmer has the denser canopy at 43.0%.
Which has better air quality, Ajmer or Jhānsi?
Jhānsi right now, at AQI 67 against 70 — a gap of 3 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?
Ajmer needs about 0 more to reach its canopy target, and Jhānsi about 1,248. 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.
