Air quality today
What is the air like in Tripoli and Tyre right now?
Tyre has cleaner air than Tripoli right now: AQI 76 (Moderate) against 125 (Unhealthy for sensitive groups). PM2.5 is setting the index in both.
Tripoli's PM2.5 is about 2.5× the WHO's 24-hour guideline of 15 µg/m³. Tyre's PM2.5 is about 1.5× the WHO's 24-hour guideline of 15 µg/m³.
Tyre is read from a nearby ground station and Tripoli is a model estimate, so the two are not quite like for like.

Deforestation · 2001–2025
Which has lost more forest, Tripoli or Tyre?
Tyre has lost more: about 120 ha of forest within 10 km of its center from 2001 to 2025, against 49 ha around Tripoli. 118 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: 2009, with 7 ha lost.
Worst year: 2024, with 22 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
Tripoli vs Tyre: your questions answered
Is Tyre cleaner than Tripoli?
On air quality, yes, right now: Tyre reads AQI 76 against 125, a gap of 49 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, Tyre averaged AQI 33 against 54, and it was the cleaner of the two on 7 of those days.
Is it safe to exercise outdoors in Tripoli and Tyre today?
In Tripoli, at AQI 125: Sensitive groups should limit long or intense outdoor activity. In Tyre, at AQI 76: Unusually sensitive people should consider limiting long outdoor exertion.
Which has lost more forest, Tripoli or Tyre?
Tyre has lost more: about 120 ha of forest within 10 km of its center from 2001 to 2025, against 49 ha around Tripoli. 118 ha of that was cleared for good, for farms, mines or towns.
Which has more trees, Tripoli or Tyre?
Tyre has more tree cover: 13.8% of the land within 2 km of its center against 11.0% around Tripoli, or about 7,804 trees against 34,558. Both figures describe the same-sized circle of ground around each center, not the whole municipality.
How many more trees do Tripoli and Tyre need?
Tripoli needs about 75,398 more to reach its canopy target of 35%, and Tyre about 9,161 to reach 30%. The target starts at 30% of the land and rises where air quality is poor.
Are Tripoli and Tyre 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. Tyre is read from a nearby ground station and Tripoli 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 Tripoli vs Tyre 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 16, 2026 and Sep 16, 2026), and the forest figures are published yearly.
