Session 10B From Combustion to Composition: New Insights into Smoke Chemistry from WE-CAN, FIREX and Other Recent Efforts—Part I

Thursday, 10 January 2019: 8:30 AM-9:30 AM
North 126A (Phoenix Convention Center - West and North Buildings)
Host: 21st Conference on Atmospheric Chemistry

Though open fires emit a suite of pollutants into the atmosphere, the chemical and physical processes that dictate the chemical evolution of smoke are only poorly understood. As a result, there have been several recent campaigns focused on particular aspects of the atmospheric evolution of smoke. We welcome presentations that describe recent advances in our understanding of these processes based on field, laboratory or satellite observations. We also welcome modeling studies across various spatial and temporal scales.

8:30 AM

8:45 AM
Observations of Major Carbon Species in Western US Wildfire Smoke Plumes during July and August, 2018
