Ecoregions are based on fauna living in European inland waters
In year 2000 representatives of the atlas groups mapping the European vascular plants, mammals, birds, amphibians, reptiles, fungi and invertebrates agreed to use the CGRS as a common grid for species distribution mapping. The CGRS grid is modified from the Military Grid Reference System (MGRS). The MGRS itself is an alphanumeric version of a numerical UTM (Universal Transverse Mercator) or UPS (Universal Polar Stereographic) grid coordinate.
Climate quality index:
Structural analysis 1961-1990
The CORINE Land Quality project (Version 1990) is an assessment of land quality in southern Europe based on four factors: soil, climate, slopes, land improvements.
The Digital Map of European Ecological Regions DMEER- delineates and describes ecological distinct areas in Europe, on the basis of climatic, topographic and geobotanical European data, together with the judgement of a large team of experts from several European nature related Institutions and the WWF
The Corine biotopes (Version 2000) database is an inventory of major nature sites
The CORINE Soil Erosion Risk project (Version 1990) is an assessment of the potential and actual soil erosion risk in Southern Europe based on four factors: soil, climate, slopes and vegetation.
Assessment of the potential soil erosion risk in Southern Europe by combining three sets of factors: soil, climate, steepness
Corine European soil database version 2
ETOPO5 was generated from a digital data base of land and sea- floor elevations on a 5-minute latitude/longitude grid
The dataset on soil contamination contains information provided on a regular basis by EIONET countries on the following issues:
Progress in the management of contaminated sites;
Expenditure and estimated costs;
Industrial and commercial branches responsible for local soil contamination;
Main contaminants affecting soil and groundwater
GISCO administrative boundaries (NUTS) v9 generalised using the 1 km reference grid for the Land cover accounts project (LEAC)
The contour line layer makes it possible to identify lowlands which are vulnerable to significant sea level rise and the risk of flooding
.
Left chart: The extent of land take during 2012-2018 (in % of the 2012 value) in floodplains of the FUAs is presented in the barchart, broken down by countries and protection type. The dataset covers the entire EEA-39 region but the figure only presents EU-27+UK countries.
Right map: Land take is derived from comparing the Urban Atlas 2012 and 2018 datasets of the Copernicus Land Monitoring Service. Land take is expressed as the converted area in % of the 2012 land cover extent (% of non-urban land cover in 2012 that is converted to urban land cover by 2018). The dataset covers the entire EEA-39 region but the Figure only presents EU-27+UK countries.
The index reports the total number of days per year with a critical level of fire danger. Fire danger is based on the Canadian Fire Weather Index (FWI) which is one of the most commonly used fire indices globally. It is based on a numerical rating of the potential frontal fire intensity and combines the rate of fire spread with the amount of fuel being consumed. The calculation of FWI requires several meteorological input variables (see the ETC-CCA Technical Paper for details).
FWI values are classified into several fire danger classes. According to the classification of the European Forest Fire Information System (EFFIS; EC, 2020), FWI values in the range 11.2-21.3, 21.3-38 and 38-50 represent ‘moderate’, ‘high’ and ‘very high’ fire risk, respectively. However, different classifications are being used at national levels. The index presented here shows the annual number of days with high fire danger conditions (defined as daily FWI values above 30 in the underlying CDS dataset).
The frequency of extreme precipitation refers to the total number of days in a year with total precipitation exceeding the 99th percentile of the daily precipitation values during the reference period. Other implementations of this index may use a different percentile (e.g., 95th) depending on the level of rarity of events to be considered.
The frost days index is defined as the number of days in a year with a daily minimum temperature below 0°C. Variations of this index limit the counting of frost occurrences to particular seasons (e.g., the growing season or the spring months). A closely related index is ‘ice days’, which uses daily maximum instead of minimum temperature.
The growing degree days index represents a measure of the accumulated heat available for vegetation growth. It is calculated as the accumulated sum over the year of the daily mean temperature exceedances of a base threshold (see the ETC-CCA Technical Paper for details). A base temperature of +5 °C is considered as representative for most European crops. Other definitions of the index are possible, including variations of the minimum temperature, the use of an upper temperature threshold, and restrictions to a given growing season.
