Frequently asked questions
How is the air quality in Denver today?
It is currently poor (European index 62). PM2.5 is 22 µg/m³, PM10 is 23 µg/m³ and ozone is 16 µg/m³. The average for the next 24 hours is around 47.
What does the European Air Quality Index (EAQI) mean?
The EAQI is a scale used by the European Environment Agency. Up to 20 is excellent air, up to 40 good, up to 60 moderate, up to 80 poor, up to 100 very poor, and above 100 extremely poor. The index is calculated from the concentration of fine particles (PM2.5 and PM10), ozone, nitrogen dioxide and sulphur dioxide.
What are PM2.5 and PM10 particles?
They are tiny particles in the air with a diameter of up to 2.5 and 10 micrometres. They come from traffic, heating and industry, and there are the most of them in winter, on calm days without wind or rain. PM2.5 is more dangerous because it penetrates deep into the lungs.
Are these measurements or estimates?
This is an atmospheric model estimate (Open-Meteo / CAMS) for the city location, not a reading from a local station. Values may therefore differ from station data in some parts of the city.
When is the air cleanest?
The air is usually cleaner during stronger winds, after rain and in the afternoon, when the cold layer near the ground breaks up. It is worst early in the morning and in the evening in the cold part of the year, when heating and traffic increase.
