Air quality maps

Neither the European Commission nor ECMWF nor meteoblue is responsible for any use that may be made of the information presented here. predictions are issued from an atmospheric model with 12 km resolution. Outputs may not be correlated enough with real concentrations. Please consult your local air quality agency, especially in the case of a pollution peak or a pollution alert.

Generally, our maps are colored according to possible health impacts on humans. The scales start with green (no/low health impact) to dark red (severe health impact).

Air quality index

Air quality index

This map shows the expected quality of air with the air quality index, that is divided in five classes,  visualized with colours as shown in the map legend. Lower values mean better air quality, whereas an index greater than 100 (orange) indicates polluted air. More: see air quality.

Ozone concentration

Ozone concentration

This map shows the expected ozone concentration, expressed in microgram per cubic meter (μg/m3). It is displayed with colours, that are specified in the legend. Combining the ozone concentration maps with line plots such as streamlines for instance may give information about where ozone is transported. More: see ozone concentration.

Pollen

Grass pollen

These maps show the expected grass, birch and olive pollen concentration with colours as indicated in the map legend. Pollen is dispersed by air currents and can be transported over large distances. We thus show the pollen forecast overlayed with the 10 m wind speed. More: see pollen.

Desert dust concentration

Desert dust concentration

This map shows the expected concentration of desert dust with colours as indicated in the map legend. The concentration is given in microgram per cubic meter (μg/m3). More: see desert dust concentration .

PM10 and PM2,5

PM10

These maps show the expected particulate matter (PM) concentration with colours as indicated in the map legend. Atmospheric particulate matter are microscopic solid or liquid matter suspended in the air. More: see PM10 and PM2,5.

SO2

SO2

This map shows the expected SO2 (sulfur dioxide) concentration with colours as indicated in the map legend. Sulfur dioxide is a gas, which is invisible and has a nasty, sharp smell. About 99% of the sulfur dioxide in air comes from human sources. 

SO2 and other sulfur oxides can contribute to acid rain which can harm sensitive ecosystems. More: see SO2.

CO

Carbon monoxide

This map shows the expected CO (carbon monoxide) concentration with colours as indicated in the map legend. Carbon monoxide is a colorless, odorless, and tasteless gas that is slightly less dense than air. Carbon monoxide is present in small amounts in the atmosphere, chiefly as a product of volcanic activity but also from natural and man-made fires (such as forest and bushfires, burning of crop residues, and sugarcane fire-cleaning). More: see CO.

NO2

NO2

This map shows the expected NO2 (nitrogen dioxide) concentration with colours as indicated in the map legend. Nitrogen dioxide is one of several nitrogen oxides. NO2 is introduced into the environment by natural causes, including entry from the stratosphere, bacterial respiration, volcanos, and lightning. More: see NO2.

Aerosol optical depth

Aerosol optical depth at 550 nm

This map shows the expected total aerosol optical depth (dimensionless) with light of wavelength 550 nm. The aerosol optical depth is visualised with colours as shown in the map legend. More: see aerosol optical depth.
