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.
