SPOT VEGETATION ten daily synthesis (provider:Vlaamse Instelling voor Technologisch Onderzoek (VITO)) [+]Topic: imageryBaseMapsEarthCover;
Extent Name: Entire Earth
Description: Since its successful launch onboard the SPOT 4 satellite in March 1998, the VEGETATION instrument is dedicated to the daily observation of terrestrial ecosystems and the biosphere, particularly for addressing global change and environment issues. The decision of the VEGETATION Programme to launch VEGETATION 2 onboard SPOT 5 in April 2002, further guarantees the continuation of the VEGETATION mission until 2008. |
stochastic simulations of soil properties at 450 sites (provider:Alterra-soil) [+]Topic: environment;
Extent Name: EU25+5
Description: The data are stochastic simulations of seven soil properties (pH, organic carbon, clay, sand, bulk density, total nitrogen and thickness) for the A, B and C horizons at 450 sites within EU25+5. Simulations were obtained with the same geostatistical model that was used to make predictions (AFOLU dataset #213) and using the same observations derived from the ISRIC WISE/SPADE dataset (http://www.isric.org) and the EFSDB dataset. Simulated values refer to stochastic simulations from the probability distribution of each soil property. In total 500 simulations were made at each of the 450 sites. Files simXXX.csv store simulations at all 450 sites taking all observations into account and using mapped landuse as a covariate. Files simXXXArable.csv, simXXXGrass.csv and simXXXNature.csv store simulations at the 150 sites of the particular landuse only, using only observations with the same landuse and not taking mapped landuse as a covariate into account. XXX is an index that refers to the simulation number (i.e. XXX is a number between 001 and 500). |
The European Soil Data Base (provider:European Soil Bureau) [+]Topic: environment;
Extent Name: Pan Europe
Description: The European Soil Database consists of a geographical data set, a semantic data set, a soil profile analytical database, a soil hydraulic parameters database and a knowledge database. It represents a first step in the development of
a fully integrated European Soil Information System (EUSIS). |
Total fertilizer input for HSMUs (provider:JRC (Joint Research Centre) - Institute for Environment and Sustainability - Climate Change Unit) [+]Topic: environment;farming;geoscientificinformation;
Extent Name: EU27 (excluding Cyprus and Malta)
Description: Nitrogen input is distributed over the spatial units on the basis of (-) regional data for mineral fertilizer consumption and national application rates per country and crop (FAO/IFA) (-) livstock density downscaled into the spatial unit and estimated total nitrogen excretion and nitrogen losses before aplication (-) other nitrogen input (atmospheric deposition, biological N-fixation) (-) irrigated and rainfed potential yield on the basis of environmental conditions. In simple terms, manure is distributed on the basis of the crops N requirement and N-availability in vicinity of the spatial unit. Mineral fertilizer nitrogen is added according to crops need. Total availability of nitrogen is exhaused by scaling regional application rates. Details are found in Leip et al. (2008). |
xmeta_regions_biof (provider:JRC-IES-CCU) [+]Topic: environment;farming;
Extent Name: EU27_noMT-CY
Description: For each calculation unit, the difference of direct N2O fluxes (BIOF_gross) is calculated against a reference land use. As reference land use (and reference N2O fluxes) fallow land is used. For regions with no fallow land, extensive grazing is used instead. The difference is referred to as BIOF_net. Crop considered are given below. The average net N2O flux over all crops and countries gives the default net N2O flux. For each region and crop, the difference to the defaul N2O flux is calcualted as BIOF_diff. Crop considered: SWHE (Soft wheat), DWHE (Durum wheat), RYEM (Rye and meslin), BARL (Barley), OATS (Oats and summer cereal mixes), MAIZ (Grain maize), OCER Other cereals including triticale), RAPE (Rape), SUNF (Sunflower), SOYA (Soya), GRAE (Gras and grazings extensive), GRAI (Gras and grazings intensive), FALL (Fallow land), REF (Reference land use) |
The
mission of the JRC is to provide customer-driven scientific and
technical support for the conception, development, implementation and
monitoring of EU policies. As a service of the European Commission, the
JRC functions as a reference centre of science and technology for the
Union. Close to the policy-making process, it serves the common
interest of the Member States, while being independent of special
interests, whether private or national.
