Oxidized organic molecules originating from the Amazon rainforest are crucial components contributing to the formation of aerosol particles in the tropical free troposphere, according to a new study led by the University of Helsinki.

Aerosol particles in the tropical free troposphere are known for their significant impact on global climate by serving as a large source of cloud condensation nuclei. However, the origin of these aerosol particles has remained unclear.

The latest research published in National Science Review demonstrated the presence of low-volatile organic compounds in the free tropospheric air from the Amazon, which sheds light on the formation of aerosol particles in this region.
