Influence of Australian Black Summer smoke in Antarctic aerosol collected on board during the R/V Laura Bassi first campaign in the Ross Sea
Biomass burning has been recognized as the largest source of primary fine carbonaceous particles, influencing the climate system and the Earth’s solar balance. During the 2019-2020 Australian bushfire season, and particularly from December to January, a lot of wildfires impacted the South-East of Au...

Biomass burning has been recognized as the largest source of primary fine carbonaceous particles, influencing the climate system and the Earth’s solar balance.
