Interpolated air quality data

Data Created 22 May 2013 Published 23 May 2013 Last modified 23 May 2013, 10:50 AM
Topics: ,
Interpolated maps showing air quality in Europe. The dataset has been reorganised in order to improve data harmonization among years and to facilitate storage and processing of the interpolated maps for the EEA data services.

Metadata

Additional information

The maps are derived primarily from Airbase background station monitoring data, few EMEP station monitoring data, supplemented with altitude, meterological ECMWF data and EMEP concentration modeling data. These maps are assessment tools for use at the European scale. They may show results which differ from assessments made at national scale.

Exposure of ecosystems to acidification, eutrophication and ozone Exposure of ecosystems to acidification, eutrophication and ozone This indicator shows the negative impact of air pollution on ecosystems and vegetation in Europe. In particular, it shows: Ecosystem areas with exceedances of the critical loads for acidification and eutrophication; and Exposure of areas covered with vegetation (crops and forests) to ground-level ozone; last year rural concentrations of ozone; and the annual variation at the European level of the rural concentrations of ozone.   In the case of acidification and eutrophication, the area as well as the magnitude of critical loads exceedances in ecosystems are shown. A critical load is a quantitative estimate of an exposure to one or more pollutants, below which significant harmful effects on specified sensitive elements of the environment do not occur according to present knowledge (ICP on Modelling and Mapping, 2015; UNECE, 2015). It represents the upper limit of one or more pollutants, deposited to the Earth's surface, that an ecosystem, such as a lake or a forest, can tolerate without being damaged in its function (for example, the nutrient nitrogen cycle) or its structure (for example, with respect to plant species' richness). A positive difference between the deposition loads of acidifying and/or eutrophying airborne pollutants and the critical loads is termed an 'exceedance'. In the case of ozone, the risk is estimated by reference to the 'critical level' for ozone for each location. This is a concentration of ozone in the atmosphere, above which direct adverse effects on receptors, such as human beings, plants, ecosystems or materials, may occur according to present knowledge (ICP on Modelling and Mapping, 2015; UNECE, 2015).
