2. EPA Black Carbon Report to Congress
Report due Congress 3/11, delivered 3/2012
Arctic warming driver of climate change
Adverse health effects of BC & PM
Covers fire extensively- US & Global
Prescribed fire control strategies
“Biomass burning” is a major contributor and focus for control worldwide

5. Transport of Black Carbon to the Arctic
Depends on:
Source location
Plume injection height
Timing with respect to weather patterns
Other factors (like rain out, chemistry)

6. % Days with Any Transport Potential
Focusing only on the ability of the atmosphere to transport the emissions to the Arctic

7. Springtime Transport Potential
The relative importance of a source for impactsing the Arctic depends on the relative source strength and the ability for the emission to be transported to the Arctic

10. Trajectory Modeling 30 yrs (1980-2009)
~2000 CONUS starting locations at multiple plume heights
Source agnostic (can be used to examine any emissions source type)
