Here is the pdf presentation by Sara.
A recording of the talk is available here.
All vegetation emits biogenic volatile organic compounds (BVOCs) which via oxidation, contribute to aerosol formation in the atmosphere. These aerosols affect climate both by reflecting incoming radiation directly and by acting as cloud condensation nuclei and thus affecting the properties of the clouds. These aerosols are especially important for climate for two reasons: 1) the emissions are highly dependent on temperature, thus initiating various feedback mechanisms, and 2) the effect of anthropogenic aerosol emissions on climate is highly dependent on the baseline aerosol state of which organic aerosols from BVOC play an important role.
In recent years, these processes have been making their way into Earth System Models (ESMs). In this presentation I will discuss what ESMs tell us about the magnitude of the BVOCs climate impact and how and why this magnitude is still very uncertain.
