The main objective of this part of the EVERGREEN work is to review available information pertaining to global emissions invento- ries of CO 2 , CH 4 and CO for the years 1990 and 2003 (or the nearest available year) (12 months of the ENVISAT mission), and to compile datasets on GHG emissions that can be used by other groups involved with project components concerning modeling, etc. The desired spatial and temporal resolution is 1x1 degree, and monthly whenever possible. A number of the currently available global databases have been considered, including relevant IGBP GEIA (Global Emission Inventory Activities) datasets, the EDGAR 3.2 database on anthropogenic emissions produced by the group at RIVM in the Netherlands, datasets published by the UNFCCC/IPCC, and those compiled within the EU POET project. Most of these databases deal with emissions from anthropogenic activities and/or emissions from biomass burning associated with agriculture, etc. In addition, recent work on emissions from biomass burning (e.g. [1, 2]), and CO 2 fluxes from oceans [3] has been incorporated. Data on anthropogenic emissions are typically compiled at the national level, using appropriate emission factors for various sectoral activities and source types. With respect to the emissions inventories for recent years in particular, the available databases are generally incomplete, and work has been undertaken within EVERGREEN to evaluate and in some cases fill the gaps in, for example, the UNFCCC datasets. For modelling purposes, national emission totals are not sufficient, and spa- tially distributed (gridded) emissions datasets are required.
