Air quality today
What is the air like in Radom and Warsaw right now?
Radom has cleaner air than Warsaw right now: AQI 62 (Moderate) against 73 (Moderate). PM2.5 is setting the index in both.
Radom's PM2.5 is about 1.0× the WHO's 24-hour guideline of 15 µg/m³. Warsaw's PM2.5 is about 1.4× the WHO's 24-hour guideline of 15 µg/m³.
Both readings come from nearby ground stations.

Deforestation · 2001–2025
Which has lost more forest, Radom or Warsaw?
Radom has lost more: about 396 ha of forest within 10 km of its center from 2001 to 2025, against 144 ha around Warsaw. 51 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: 2007, with 52 ha lost.
Worst year: 2010, with 20 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
Radom vs Warsaw: your questions answered
Is Radom cleaner than Warsaw?
On air quality, yes, right now: Radom reads AQI 62 against 73, a gap of 11 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 6 days, on modeled daily averages, Radom averaged AQI 90 against 112, and it was the cleaner of the two on 6 of those days.
Is it safe to exercise outdoors in Radom and Warsaw today?
The advice is the same for both today. Unusually sensitive people should consider limiting long outdoor exertion. Radom reads AQI 62 and Warsaw reads AQI 73.
Which has lost more forest, Radom or Warsaw?
Radom has lost more: about 396 ha of forest within 10 km of its center from 2001 to 2025, against 144 ha around Warsaw. 51 ha of that was cleared for good, for farms, mines or towns.
Which has more trees, Radom or Warsaw?
Radom has more tree cover: 27.9% of the land within 2 km of its center against 26.9% around Warsaw, or about 87,037 trees against 82,988. Both figures describe the same-sized circle of ground around each center, not the whole municipality.
How many more trees do Radom and Warsaw need?
Radom needs about 6,551 more to reach its canopy target of 30%, and Warsaw about 9,564 to reach 30%. The target starts at 30% of the land and rises where air quality is poor.
Are Radom and Warsaw 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 Radom vs Warsaw 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 13, 2026 and Sep 18, 2026), and the forest figures are published yearly.
