The good category means that pollutants are present at low concentrations in the air.

The moderate category indicates that air quality still does not suppose a health risk.

The poor category means that air quality is near to exceed the limit values and therefore it should be reduced the exposure time outdoors.

The bad category indicates that a limit value for the specified time period is exceeded, according to the air quality laws for the human health protection (2008/50/CE Directive).

Finally, the very bad category implies that air quality may involve an imminent risk for the most vulnerable people (children, the elderly and those with cardiopulmonary diseases) with the exceedance of alert thresholds (2008/50/CE Directive).

Welcome to the mobile application for the Air Quality Operational System for Spain (CALIOPE) from the Barcelona Supercomputing Center - Centro Nacional de Supercomputación (BSC-CNS).

With this application you will be able to check the air quality forecast for Europe, besides the concentration maps in the next 24 hours for the main pollutants: ozone (O3), nitrogene dioxide (NO2), sulfur dioxide (SO2) and particulate material (PM10 y PM2.5). The AQI is calculated hourly for the O3, NO2 and SO2, for the shown time; for PM10, PM2.5 and CO, the calculation is performed over the last 24 hours mobile average for the PM10 and PM2.5, and over the last 8 hours mobile average for the CO.

The App will show you the air quality forecast for the 10 nearest stations to your location (you should enable your device's GPS), giving it a value for each pollutant, according to one of these fice categories: good, moderate, poor, bad and very bad. These categories are stablished according to the next concentration ranges.

AQI O3 NO2 SO2 PM10 PM2.5
Good 0-100 0-35 0-70 0-25 0-15
Moderate 100-130 35-80 70-125 25-40 15-25
Poor 130-180 80-200 125-350 40-50 25-40
Bad 180-240 200-400 350-500 50-75 40-60
Very bad ≥240 ≥400 ≥500 ≥75 ≥60

* The table values are expressed in ug/m3

In this link you can find more information about the categories and the health risks they entail.

In the map, markers with the Ο icon are representing stations, while the ones with the ∇ icon represent towns without observational air quality data.

Troposheric ozone is a colorless gas made of three atoms of oxygen and created through photochemical and chemical reactions betweeen nitrogen oxides (NOx) and volatile organic compounds (VOCs). It is the most important of the photochemical oxides and a constituent of photochemical smog. The exposition to high concentrations of ozone for long periods can harm human health, so it can provoke eye and throat irritation, reduced lung function, agravation of asthma...

Nitrogen dioxide it is a reddish-brown toxic gas. It is formed as a subproduct in most combustion processes at high temperatures, like in motor vehicles or industrial combustion. It reacts on atmosphere to form ozone (O3) and acid rain. Short time exposition at high levels, as well as long time exposition at lower leves can damage lung cells.

Sulfur dioxide is an irritant and toxic gas. The most of it is produced by basic combustion processes, given that fuels like coal, petroleum, diesel and gasoline contain sulfur compunds. As it is mainly absorved through the respiratory system, short expositions at high concentrationsos can irritate the respiratory tract, cause bronchoconstriction and increased asthma symptom.

Particulate matter air contamination is a combination of microscopic solid and liquid matter suspended in the Earth's atmospher. These particles exist in many different sizes and shapes and can be compund by hundreds of different chemical substances. PM2.5 & PM10 denomination refer to the size of the particles. PM2.5, or "fine particles" refer to those of 2.5 micrometres at most. These particles can penetrate deeply into sensitive parts of the lungs and can cause of worsen respiratory disease. Exposition to fine particles has been associated to serious health problems, varying from asthma symptom increase to the development of a chronic bronchitis, or cardiac arrythmia, hearth attacks and even premature death.
