Reading these numbers
How this comparison is made
Air quality index
The US EPA index, computed from current pollutant concentrations: ground stations where a place has them nearby, and the CAMS atmospheric model everywhere else. It moves hour to hour, so it is a snapshot rather than a verdict on either place. The guideline marks are from the WHO's 2021 air quality guidelines.
Trees and forest
Tree cover is the share of ground under canopy within 2 km of each center, read from Sentinel-2 satellite imagery at 10 m detail. It measures that circle, not the whole municipality, which is what makes the two comparable. Forest loss comes from the University of Maryland's Global Forest Change maps.
More on the method on the About Airleaf page.
Frequently asked
Ahmedabad vs Mumbai: your questions answered
Is Ahmedabad cleaner than Mumbai?
On air quality, yes, right now: Ahmedabad reads AQI 119 against 126, a gap of 7 points on the US EPA index. This is a live reading rather than an annual average, so it can reverse within a day. Over the past 7 days, on modeled daily averages, Ahmedabad averaged AQI 87 against 136, and it was the cleaner of the two on 7 of those days.
Is it safe to exercise outdoors in Ahmedabad and Mumbai today?
The advice is the same for both today. Sensitive groups should limit long or intense outdoor activity. Ahmedabad reads AQI 119 and Mumbai reads AQI 126.
Which has more trees, Ahmedabad or Mumbai?
Mumbai has more tree cover: 14.9% of the land within 2 km of its center against 12.4% around Ahmedabad, or about 45,874 trees against 37,670. Both figures describe the same-sized circle of ground around each center, not the whole municipality.
How many more trees do Ahmedabad and Mumbai need?
Ahmedabad needs about 68,657 more to reach its canopy target of 35%, and Mumbai about 61,883 to reach 35%. The target starts at 30% of the land and rises where air quality is poor.
Are Ahmedabad and Mumbai measured the same way?
The method is the same: the US EPA index for air, and Sentinel-2 satellite imagery at 10 m detail over an identical radius for trees. Both readings come from nearby ground stations. Nothing is adjusted for population, city limits or climate.
How often does the Ahmedabad vs Mumbai comparison update?
The air readings refresh about once an hour, and each reading's local time is shown at the top of the page. Tree cover comes from the latest clear satellite image of each area (Oct 15, 2026 and Oct 23, 2026), and the forest figures are published yearly.
