Air quality today
What is the air like in Khulna and Rangpur right now?
Khulna has cleaner air than Rangpur right now: AQI 68 (Moderate) against 162 (Unhealthy). PM2.5 is setting the index in both.
Khulna's PM2.5 is about 1.2× the WHO's 24-hour guideline of 15 µg/m³. Rangpur's PM2.5 is about 5.4× the WHO's 24-hour guideline of 15 µg/m³.
Khulna is read from a nearby ground station and Rangpur is a model estimate, so the two are not quite like for like.

Deforestation · 2001–2025
Which has lost more forest, Khulna or Rangpur?
Rangpur has lost more: about 6 ha of forest within 10 km of its center from 2001 to 2025, against 2 ha around Khulna. 2 ha of that was cleared for good, for farms, mines or towns.
Measured within 10 km of each center, from the yearly satellite maps of forest loss: a wider circle than the one for tree cover, because forest is usually lost at a city's edges.
Worst year: 2018, with under 1 ha lost.
Worst year: 2007, with 1 ha lost.

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
Khulna vs Rangpur: your questions answered
Is Khulna cleaner than Rangpur?
On air quality, yes, right now: Khulna reads AQI 68 against 162, a gap of 94 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 6 days, on modeled daily averages, Rangpur averaged AQI 142 against 145, and it was the cleaner of the two on 2 of those days.
Is it safe to exercise outdoors in Khulna and Rangpur today?
In Khulna, at AQI 68: Unusually sensitive people should consider limiting long outdoor exertion. In Rangpur, at AQI 162: Everyone should limit long outdoor exertion; sensitive groups more so.
Which has lost more forest, Khulna or Rangpur?
Rangpur has lost more: about 6 ha of forest within 10 km of its center from 2001 to 2025, against 2 ha around Khulna. 2 ha of that was cleared for good, for farms, mines or towns.
Which has more trees, Khulna or Rangpur?
Rangpur has more tree cover: 59.6% of the land within 2 km of its center against 38.9% around Khulna, or about 185,554 trees against 108,887. Both figures describe the same-sized circle of ground around each center, not the whole municipality.
How many more trees do Khulna and Rangpur need?
Khulna needs about 0 more to reach its canopy target of 30%, and Rangpur about 0 to reach 40%. The target starts at 30% of the land and rises where air quality is poor.
Are Khulna and Rangpur 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. Khulna is read from a nearby ground station and Rangpur is a model estimate, so the two are not quite like for like. Nothing is adjusted for population, city limits or climate.
How often does the Khulna vs Rangpur 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 12, 2026 and Oct 20, 2026), and the forest figures are published yearly.
