About Paruso · Air quality, pollen & UV
Paruso gives you a clean, fast answer to one everyday question: what's the air like where I'm going, and should hay-fever be on my radar, and how strong is the sun?
What we cover
For 738 European cities we publish the current European Air Quality Index (EAQI), the main pollutants (PM2.5, PM10, NO₂, ozone) and six pollen types (grass, birch, olive, mugwort, alder, ragweed), plus a short multi-day outlook. You can also look up any other place in Europe live from the home page.
Where the data comes from
All figures come from the Copernicus Atmosphere Monitoring Service (CAMS) European model, accessed through the open Open-Meteo API - covering the European Air Quality Index, the main pollutants, six pollen types and the UV index. We rebuild every page once a day.
What the values mean
The European Air Quality Index (EAQI) summarises PM2.5, PM10, NO₂ and ozone on one scale - lower is cleaner air:
Pollen is reported in grains per m³ and banded from none to very high (thresholds differ per plant). All figures are indicative and not medical advice.
Independence
Paruso is independent and free to use, with no account required. Some outbound product links may be affiliate links that help fund the site; they never change the data we show.
