Maps - Data
1. Masker of all files (EU27.asc)
 |
This map is a mask created including all the EU-27 countries and the Corine land-use classes 1-38 and 49. Surface waters and coastal lagoons are excluded from the mask. Legend There is only one legend unit, i.e. 1 which means that the grid cell is included. |
2. Countries of the EU-27 (countries.asc)
 |
The map shows the countries of the EU-27. It was obtained by masking the NUTS level 0 map with the mask EU27. Legend Get the Legend explanation file. |
3. Regulatory zones (zones.asc)
 |
This map shows the regulatory zones of the EU-27. The map is a reclassification of the map countries.map. Legend 1: North (Includes Countries: 17, 20, 24, 48, 50 and 67) 2: Centre (Includes Countries: 5, 8, 16, 34, 35, 49, 58, 61, 64, 68, 70 and 78) 3: South (Includes Countries: 1, 9, 23, 26, 31, 41 and 62) |
4. Corine land cover data (CLC2000.asc)
| The map shows all the possible land use classes at the Corine map. The map presented here is at a resolution of 1x1 km2, the original map was at a resolution of 0.25 km2. For each 1x1 km2 grid cell, the dominant of the four underlying grid cells was taken. The dataset is described in Nunes de Lima (2005). Legend Get the Legend explanation file. |
5. Generalised land-use map (landuse.asc)
 |
The generalised land-use map is a reclassification of the Corine 2000 land-use map. It is created to distinguish the most important land-use types. Land use class 1 serves as the masker in EFSA (2010). Legend Number - Description 1 Annual Crops 2 Grass 3 Permanent crops 4 Rice 5 Non agricultural |
6. Mean monthly temperature (T1.asc….. T12.asc)
| The dataset consists of 12 maps containing the monthly mean temperature (deg C) for the period 1960-1990. The dataset is described in Hijmans et al. (2005). Legend Mean monthly temperature (deg C), data type Real |
7. Mean annual temperature (TMean.asc)
 |
The map shows the mean annual temperature (deg C) for the period 1960-1990. It is calculating by taking the arithmetic mean of maps T1..T12.asc. The dataset is described in Hijmans et al. (2005). Legend Mean annual temperature (deg C), data type Real |
8. Arrhenius weighted mean annual temperature (TEff.asc)
 |
The map shows the Arrhenius weighted mean annual temperature (deg C) for the period 1960-1990. It is calculated using the equation (EFSA 2010, Appendix A3): where Teff (K) is the Arrhenius weighted mean annual temperature, Eact is the Arrhenius activation energy, (kJ mol-1), R (kJ mol-1 K-1) is the gas constant, T (K) is the temperature, and t is time. Eact was set to 65.4 kJ mol 1 according to EFSA (2007). See further EFSA (2010). Notice that the temperatures in the equation are in K, whereas the temperature in the maps is in deg C. Legend Arrhenius weighted mean annual temperature (deg C), data type Real |
9. Mean monthly precipitation (P1.asc.....P12.asc)
| The dataset consists of 12 maps containing the monthly mean precipitation (mm/month) for the period 1960-1990. The dataset is described in Hijmans et al. (2005). Legend Mean monthly precipitation (mm/mo), data type Real |
10. Mean annual precipitation (Ptot.asc)
 |
The map shows the mean annual precipitation for the period 1960-1990 (mm/year). It is calculated by summing P1..P12.map. The dataset is described in Hijmans et al. (2005). Legend Mean annual precipitation (mm/yr), data type Real |
11. FOCUS Zones (FOCUS.asc)
 |
The map shows the FOCUS zones according to the classification in FOCUS (2000). The maps Tmean.map and Ptot.map were used to create the overlay, so the classification is based on WorldClim (Hijmans et al., 2005). Legend
|
12. Organic matter content of the topsoil (OM.asc)
 |
The map shows the organic matter content of the topsoil. It is obtained by multiplying the original OCTOP map described in Jones et al. (2005) by 1.72. Legend Organic matter content of the topsoil (g/g), data type Real |
13. pH of the topsoil (pH.asc)
 |
The map shows the mean pH measured in water (1:2.5) of the top 30 cm of the soil. See FAO (2008) for details. Legend pH measured in water of the topsoil, data type Real |
14. Bulk density of the topsoil (Rho.asc)
 |
The map shows the bulk density of the topsoil. It is calculated from the organic matter content map using the equation (Tiktak et al., 2002): 
Legend Dry bulk density of the topsoil (kg m 3), data type Real |
15. Texture of the topsoil (Texture.asc)
 |
The map shows the textural class of the topsoil. It is obtained from the soil geographical database of Eurasia at a scale of 1:1000000 (for each grid cell, the dominant soil textural class was taken). Legend 1: Coarse (18% < clay and > 65% sand) 2: Medium (18% < clay < 35% and >= 15% sand, or 18% < clay and 15% < sand < 65%) 3: Medium fine (< 35% clay and < 15% sand) 4: Fine (35% < clay < 60%) 5: Very fine (clay > 60 %) 9: No mineral texture (Peat soils) |
16. Water content at field capacity (ThetaFC.asc)
 |
The map shows the water content at field capacity (m3 m-3). It is calculated for each soil textural class with the Mualem-Van Genuchten equation:.
where Theta (m3 m-3) is the volume fraction of water, h (cm) is the soil water pressure head, Theta s (m3 m-3) is the volume fraction of water at saturation, theta-r (m3 m-3) is the residual water content in the extremely dry range, alpha (cm-1) and n ( ) are empirical parameters, and m ( ) can be taken equal to:  The soil water pressure head was set at -100 cm. Parameter values were obtained from the HYPRES pedotransfer rule (Wösten et al. 1999) and are given in EFSA (2010). Legend Volumetric water content at field capacity (m3 m-3), data type Real. The map contains six discrete classes. |
17. Capri land cover maps (Cropnames.asc)
   |
These maps show for each pixel of 1x1 km2 the area covered with a certain crop. The CAPRI maps were obtained by combining remote sensing data, administrative crop data, land suitability data and statistical modelling. The CORINE land cover map serves as a starting point. Subdivisions within CORINE land cover classes were made based on a statistical model, regressing point observations of cropping activities on soil, relief and climate parameters (land suitability). Statistical data of agricultural production and land cover available for administrative regions were additionally used to scale the land cover classes. 18 of the CAPRI land cover classes are classified as annual crops and are included in the EFSA dataset. See Leip et al. (2008) for a description of the dataset.
Legend Area (100%) covered by a crop, data type Real. The names of the maps are self explaining. The values range from 0 to 10000. |
