Abstract: Ambient aerosols remain a serious concern in atmospheric science, as they have a deleterious impact on both the climate and human health. They have the enormous capacity to directly contribute to atmospheric heating and cooling via the absorption and scattering of incoming solar and outgoing long-wave radiation. They also have an indirect effect on the climate by serving as cloud condensation nuclei or changing the microphysical features of clouds. However, our understanding of the processes that explain these impacts is constantly evolving. We still have a limited understanding of the physical and chemical aspects of atmospheric aerosol sources and sinks. Investigating the sources and chemical transformations of ambient aerosols in real ambient conditions is often difficult due to the multiple sources and formation processes. Understanding the exact sources along with the formation pathways is crucial to responding to the changing climate and poor air quality. The talk will highlight the reaction mechanism, fate, and impacts of emitted volatile organic compounds from both natural and anthropogenic sources. The need for chamber studies, along with field-based offline as well as in-situ measurements, will be discussed in detail.
