European AQI Scale
0–20
Good
Air pollution poses little or no risk.
21–40
Fair
Acceptable for most; very sensitive people may notice symptoms.
41–60
Moderate
Children, elderly and people with conditions should limit prolonged outdoor exertion.
61–80
Poor
Everyone may start to feel effects; sensitive groups risk more serious effects.
81–100
Very Poor
Health warning of emergency conditions; everyone is more likely to be affected.
100+
Hazardous
Health alert: serious effects for everyone — limit time outdoors.

The European Air Quality Index ranges from 0 (best) to 100+ (worst). It combines measurements of particulate matter and gas pollutants into a single number.

What are these pollutants?
PM2.5Fine particulate matter smaller than 2.5 micrometers. These particles are small enough to bypass the nose and throat, reaching deep into the lungs and even entering the bloodstream. Major sources include vehicle exhaust, industrial processes, and wildfires.
PM10Coarse particles smaller than 10 micrometers, including dust, pollen, and road surface wear. While larger than PM2.5, they still cause respiratory irritation and aggravate asthma.
O₃Ground-level ozone is not emitted directly — it forms when nitrogen oxides and volatile organic compounds react in sunlight. Higher in summer afternoons. Can trigger asthma attacks and reduce lung function.
NO₂Nitrogen dioxide comes primarily from vehicle engines and power plants. It inflames the lining of the airways, making the lungs more susceptible to infection.
SO₂Sulfur dioxide is released by burning fossil fuels containing sulfur, especially coal and oil. Even short exposure can constrict airways, particularly in people with asthma.
COCarbon monoxide is an odorless gas from incomplete combustion of fuels. Outdoors, it mainly comes from vehicle traffic. At elevated levels, it reduces the blood's ability to carry oxygen.
Dust (AOD)AOD at 550nm. Above 0.3 = Saharan dust.

Air Quality FAQ

The European AQI is a number from 0 to 100+ that summarizes how clean or polluted the air is. It combines measurements of fine particles (PM2.5, PM10) and gases (ozone, NO₂, SO₂) into a single score. The higher the number, the worse the air quality and the greater the health risk.
Children, the elderly, pregnant women, and people with asthma, COPD, or heart disease are most vulnerable. Even moderate pollution levels (AQI 41–60) can trigger symptoms in these groups. Athletes and outdoor workers also face higher exposure due to increased breathing rates.
On high-pollution days: stay indoors with windows closed, use air purifiers with HEPA filters, avoid strenuous outdoor exercise (especially near busy roads), and check the AQI forecast before planning activities. Even on moderate days, sensitive individuals should limit prolonged outdoor exertion.
Ozone peaks on hot, sunny afternoons (summer). Particle pollution (PM2.5) is often worst in winter due to heating and temperature inversions that trap pollutants near the ground. Rush-hour traffic causes NO₂ spikes morning and evening. Dust events and wildfires can cause sudden, severe spikes any time of year.
