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.

Frequently asked
Kasur vs Phool Nagar: your questions answered
Is Phool Nagar cleaner than Kasur?
On air quality, yes, right now: Phool Nagar reads AQI 432 against 801, a gap of 369 points on the US EPA index. This is a live reading rather than an annual average, so it can reverse within a day. But over the past 7 days, on modeled daily averages, Kasur averaged AQI 216 against 217, and it was the cleaner of the two on 4 of those days.
Is it safe to exercise outdoors in Kasur and Phool Nagar today?
The advice is the same for both today. Emergency conditions — avoid outdoor activity. Kasur reads AQI 801 and Phool Nagar reads AQI 432.
Which has more trees, Kasur or Phool Nagar?
Kasur has more tree cover: 10.8% of the land within 2 km of its center against 7.3% around Phool Nagar, or about 33,929 trees against 22,934. Both figures describe the same-sized circle of ground around each center, not the whole municipality.
How many more trees do Kasur and Phool Nagar need?
Kasur needs about 107,442 more to reach its canopy target of 45%, and Phool Nagar about 118,438 to reach 45%. The target starts at 30% of the land and rises where air quality is poor.
Why can two places 49 km apart read differently?
Air changes over short distances with traffic, industry, wind and hills, and each reading comes from the nearest ground stations or, where there are none, from a regional model. A gap of a few points between neighbors is within normal variation, while a gap that crosses an EPA band is worth noticing.
Are Kasur and Phool Nagar 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 Kasur vs Phool Nagar 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 (Sep 8, 2026 and Sep 11, 2026), and the forest figures are published yearly.
