There is a significant connection between biomass burning (BB) emissions, the terrestrial environment and the atmosphere, which has strong implications for feedbacks to the climate system and air quality. BB has the potential to alter numerous land and atmospheric processes that, in turn, feedback to and interact with the climate system (i.e. black carbon on spring Arctic ice, vegetation change alters albedo). The heights to which BB smoke is injected governs short- or long-range transport, which influences surface pollution, cloud interaction (altered albedo), and modifies patterns of precipitation (cloud condensation nuclei). We are working with partners, primarily the EPA and regional partners, to generate BB plume injection heights using multiple satellite platforms that have the capacity to provide parameters that will support the enhancement of plume injection height in models. We present: (1) a methodology that links BB injection height and CALIOP air parcels to specific fires; (2) the daily evolution of smoke plumes; and (3) compare CALIOP-derived smoke plume injection to CMAQ modeled smoke plume injection. Statistics that link fire behavior and weather to plume rise are crucial for verifying and enhancing plume rise parameterization in local-, regional- and global-scale models used for air quality, chemical transport and climate.
