  1. 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

  2. Figure A. BC Emissions by Major Source Category. (Source: Lamarque et al., 2010 and U.S. EPA)

  3. 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)

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

  5. 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 Rx Fire Emissions 2008-2011 % Mar-May days with Transport

  6. Daily Forecasts

  7. 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)
