#203 - Atmospheric Aerosols and Particle Studies (09007)
This session on "Atmospheric Aerosols and Particle Studies" is meant as a more focused addition to the session formerly known as "Homogeneous and Heterogeneous Atmospheric Chemistry" and currently re-titled "Atmospheric Chemistry and Physics". It is intended for researchers wishing to present work on any aspect of chemical or physical processes in the atmosphere related to particulate matter or aerosols. For research more broadly related to atmospheric science, please consider the related session "Atmospheric Chemistry and Physics".
