Abstract:

The land surface exerts an important influence on atmospheric composition through the emission and uptake of reactive volatile organic compounds (VOCs). Quantifying these emission rates and the subsequent atmospheric impacts is a major challenge and an important source of uncertainty in current models. In this talk, I will present results from our recent studies using a combination of new tall tower and space-based observations to derive top-down information on VOC source processes. The talk will focus in particular on measurements from the UMN Tall Tower Observatory and the Aura TES platform, and will explore the constraints these data can provide on the distribution of key biogenic (methanol, formic acid) and anthropogenic (aromatic compounds) VOC sources to the atmosphere.
