Mercury emissions to air from anthropogenic sources in 2010, globally gridded (0.25 by 0.25 degrees in both kg per grid cell and g per km2), with component data for three mercury species classes (Hg0, Hg(II) and particulate bound HgP) and for three emission height classes (0-50, 50-150 and >150m) in four emission sector groups: energy production (POWERGEN), industrial sectors (INDS), waste from intentional use (INTWASTE) and artisanal and small-scale gold mining (ASGM).

During the preparation of the AMAP/UNEP inventory of mercury emissions to air from anthropogenic sources in 2015, the 2010 inventory, originally compiled in 2013 as part of the work undertaken in connection with the UNEP Global Mercury Assessment 2013 (AMAP/UNEP, 2013) was updated. This update took account of new information and include additional sectors introduced in the 2015 inventory (see AMAP/UN Environment, 2019). This revised 2010 inventory was spatially distributed to produce the 2010 v2 dataset which is the subject of this documentation.

The 2010 v2 inventory is considered more complete than the 2010 v1 inventory (available from AMAP (https://www.amap.no/work-area/document/862). It was geo- spatially distributed using the methodology applied to the 2015 inventory. However, it is necessary to note that, while point source information for 2010 was applied, this is not directly compatible with the point source information available for 2015; and 2010 diffuse emissions were distributed using the surrogate distributions applicable in 2015. More information on the comparison between the 2010 v1 and 2010 v2 spatially distributed inventories can be found in AMAP/UN Environment, 2019.
