A Note of Caution

Because different inventories prepared at different times have employed different methodologies, used different data (re)sources, and include different sets of emission sectors, it is generally not appropriate to make direct comparisons between inventory products. If such comparisons are to be made, then due account needs to be taken of their intrinsic differences.

To address this, more recent global inventories have been prepared using methods with greater transparency and more complete documentation of the sources of data used and methods employed.

Description

Global mercury emissions to the atmosphere in 2010 from anthropogenic sources (all sectors in reported inventory apart from 'contaminated sites')

AMAP/UNEP 2010 global inventory prepared for the UNEP 2013 Global Mercury Assessment

Includes additional sectors and sub-sector categorization of emissions relative to 2005 inventory.

Data set includes emissions in kg/grid cell, with an additional column containing grid cell area (in km2) that can be used to re-calculate estimates to e.g. kg/km2

(4,533,448 bytes) contains the emission model output for mercury emissions in different species/height classes; units = kg/cell

Mercury speciation: Hg0: elemental Hg; Hg2: Hg2+ species; HgP: particulate associated Hg. Height classes: _1 = 0 - 50m; _2 = 50 - 150m; _3 = >150m

File cellSurfaceArea05_14feb2013_FS.txt

(7,450,603 bytes) contains the surface area of the cell (km^2) based on an approximation (using the Haversin method). This can be used to normalize estimates to emissions per unit area.

Description

Global mercury emissions to the atmosphere in 2010 from anthropogenic sources (as per dataset 2010v1) but with separate files for three groups of emission sectors:

(1) Stationary combustions sources (power plants and distributed heating and energy uses excluding industrial uses)(includes the following sectors*: SC-PP-coal; SC-PP-oil; SC-PP-gas; SC-DR-coal; SC-DR-oil; SC-DR-gas)

(2) Industrial sources (including stationary combustion for industry)(includes the following sectors*: SC-IND-coal; SC-IND-oil; SC-IND-gas; CEM; PISP; OR; NFMP-Cu; NFMP-Pb; NFMP-Zn; NFMP-Al; NFMP-Hg; NFMP-Au)

(3) Intentional use and product waste associated sectors (includes the following sectors*: ASGM; CSP; CREM; WI; WASOTH)
