JOINT RESEARCH CENTRE EUROPEAN COMMISSION Data Quality Assessment and Control – Criteria Timeliness Completeness Consistency Transparency Comparability Accuracy Precision COMPLEXITYFEASIBILITY HIERACHICAL LEVEL VVerification

JOINT RESEARCH CENTRE EUROPEAN COMMISSION Consistency Timeliness Completeness Transparency Comparability Verification Precision Accuracy Inventory System – Data Quality Aspects MS ETC/ACC- EEA JRC EUROSTAT IPCC / Research / MS
5
JOINT RESEARCH CENTRE EUROPEAN COMMISSION Data Quality – Role of this workshop transparency / comparability: learn about the methods used in the national inventories evaluate comparability of the methods used point on inconsistencies and unexplainable differences accuracy / precision discuss advantages and disadvantages of different methodologies for national and EU inventories to be able to account for mitigation measures

JOINT RESEARCH CENTRE EUROPEAN COMMISSION N2OCH4 Anthropogenic biogenic GHG emissions in Europe (2002 submissions) Agricultural soils: 87% Enteric Fermentation: 78% Total GHG emissions (2000): 4000 Tg CO2-eq. Share of agriculture on total emissions: 10% Share of biogenic emissions: 520 Tg CO2-eq. (13%) 69% of N2O are biogenic 82% of CH4 are biogenic

JOINT RESEARCH CENTRE EUROPEAN COMMISSION Methane uptake rates in Europe (Boeckx & van Cleemput, 2001) grasslandarable landforest 0.570.350.97mg CH 4 m -2 d -1 CH4 fluxes from agricultural soils No background information Reduced capability of arable soils to act as a sink for CH4 ?
13
JOINT RESEARCH CENTRE EUROPEAN COMMISSION Direct N2O emissions from agricultural soils variations cannot be explained by input of nitrogen only: land use history application technique organic carbon,.... variability in caused by the local weather VEF of 1.25% too high?
14
JOINT RESEARCH CENTRE EUROPEAN COMMISSION N2O emissions from agricultural soils – “background emissions” two MS have included an emission of N2O from agricultural soils due to cultivation of mineral soils of 0.5 kg N2O-N ha -1 year -1 factoring-out of anthropogenic induced background emissions ? additional information required to determine level (land-use history) ? V modelling !!

JOINT RESEARCH CENTRE EUROPEAN COMMISSION Conclusions there are many questions..
