The dataset has been compiled for use by modellers for assessing the impacts of air pollutants on European ecosystems and agriculture. The information is being used by the United Nations Economic Commission for Europe (UN-ECE) and EMEP in assessing tropospheric ozone impacts.

The data has been compiled from a mixture of existing digital and paper sources including the European Environment Agency (EEA) Corine Land Cover 2000, SEI Land European Cover Map (2002 Revision), FAO Soil Map of the World, EEA European Biogeographical regions (2005).

The data have been modelled and combined to generate classes differentiating between various European Nature Information System (EUNIS) codes (http://eunis.eea.europa.eu/). The dataset contains information down to EUNIS level 3 for specific habitat types.

The LRTAP data was used to identify the extent of agricultural land (EUNIS code – I1: Arable land and market gardens) and pasture (EUNIS code – E2: Mesic grasslands) in the UK. Additional data from the IGBP was then used to differentiate crop distribution.
