Air information – current ozone levels

High temperatures during the summer months can be accompanied by elevated levels of ground level ozone. We provide up-to-date information on ozone levels for the whole of Austria.

Ozone Map

LEGEND:
Air quality measurements of the Austrian federal network and of the Austrian provinces,
compiled by the Environment Agency Austria
Based on provisional (non-validated) data
Ozone information threshold: 180 µg/m³ as one-hour mean
Ozone alert threshold: 240 µg/m³ as one-hour mean
Ozone target value: 120 µg/m³ as maximum daily eight-hour mean
(not to be exceeded on more than 25 days per year, averaged over three years)

Recommended (optional) actions in case of exceedance of the ozone information threshold:
At ozone concentrations above the information threshold, it is possible that very sensitive individuals may experience minor symptoms during strenuous physical activity.
Usual outdoor activities – e.g. walking, bathing or picnics - are safe even for vulnerable individuals.
They should, however, check the ozone forecast for their area.
Other personal precautions are only necessary if the ozone alert threshold is exceeded.

Recommended (optional) actions in case of exceedance of the ozone alert threshold:
Ozone concentrations above the alert threshold may cause irritations of the mucous membranes or breathing problems.
Unusual and strenuous physical activity, particularly at midday and in the afternoon, should be avoided.
Individuals who are at risk – such as children with bronchial hyper-reactivity, individuals with severe respiratory diseases and/or heart conditions and people with asthma – should consider staying indoors in smoke-free areas.
Please contact your doctor for personal health advice.
