Why are there so many newly formed aerosol particles in the upper troposphere over tropical regions such as the Amazon? Tropical forests play an important role in global climate regulation; however, the high concentrations of new particles above these areas have puzzled atmospheric scientists for the past 20 years.
Recent research has identified that isoprene, a naturally occurring organic compound emitted by vegetation, significantly contributes to the formation of new particles in the upper troposphere. These findings enhance our understanding of atmospheric processes and potentially aid in climate modelling.
"Our key finding is that the presence of extremely low concentrations of sulphuric acid or iodine oxoacids dramatically enhances particle formation, accelerating it up to 100 times faster compared to when only isoprene oxygenated organics are present.
"This study underscores the complex interactions between forests, the atmosphere, and climate. This demonstrates how emissions from trees can have far-reaching effects on cloud formation and potentially on the global climate. This type of fundamental research is crucial for improving our understanding of climate processes and our ability to predict and mitigate climate change," says Professor Katrianne Lehtipalo from the University of Helsinki.Jiali Shen, Douglas M.
