EMEP Steering Body, Geneva, 2014
Emissions data for modellingItem 4.3 Co-operation with TFEIP
EMEP official emissions data (Parties, CEIP):
• Time-series of national emission totals (Parties, annually)
• Gridded emissions for the latest reported year (CEIP, annually)
• Gridded sectoral emissions (Parties, once in five years)
• Emissions from Large Point Sources (Parties, once in five years)
Additional emissions data for modelling (MSC-E):
• Time-series of gridded annual emissions for 1990-2012
• Speciation of Hg emissions (Hg0, Hg(II)gas, Hg(II)part)
• Vertical distribution of anthropogenic emissions
• Emissions for the non-EMEP countries within the EMEP domain (Northern Africa and Middle East)
• Gridded emissions on a global scale (Hg)
• Natural and secondary sources (re-suspension and re-emission)
