Why Black Carbon in Northern Eurasia?
Develop a Mitigation Policy for BC Emissions
Global
• the 2nd most important species for climate forcing
• Short lifetime: ~ a week
• Sources: industry 64% , biomass burning 36%
Northern Eurasia
• Reducing surface albedo
• Absorbing solar radiation that leads to accelerated ice melting in the Arctic
• Sources: biomass burning and industries (?)
• Deposition efficiency: % (?) of emitted BC deposited on the Arctic
Objectives
• Develop high spatial (500 m x 500 m) and temporal
(daily) distribution of black carbon emissions from
fires in Northern Eurasia from 2002 to 2013
• Identify the major sources of fires in different
