Emission database for global atmospheric research (EDGAR)
article
Atmospheric chemistry and climate modellen require gridded global emissions data as input into their models. To meet this urgent need a global emissions source database called EDGAR is being developed by TNO and RIVM to estimate for 1990, on a regional and on a grid buis, anaal emissions of greenhouse gases (CO2, CH4, N20, CO, NO,, non-methane VOC, SO,), of NH3, and of ozone depleting compounds (halo-carbons) from all known sources. The aim is to establish at due levels of spatial, temporal and source aggregation the emissions from both anthropogenic and biogenic sources: a complete set of data required to estimate the total source strength of the various gases with a kl' resolution (attitude resolution of 1 km) and a temporal resolution of a month, supplemented by diurnal variation, as agreed upon in the Global Emissions Inventory Activity (GEIA) of the International Atmospheric Chemistry Programme (IGAC). In this way EDGAR win meet the requirements of present and future developments in the field of atrnospheric modelling. The data comprise demographic data, social and economie factors, land use distributions and emission factors (with due emphasis on the uncertainty). As understanding in this field is stil changing, due attention is paid to flexibility regarding the disaggregation of sources, spatial and temporal resolution and species. The objective and methodology chosen for the construction of the database and the structural design of the datithosP system are presented, as well as the type and sources of data and the approach used for data collection. As an example, the construction of the N20 inventory is discussed.
