African smoke over the Amazon
More soot particles enter the central Amazon rainforest from brush fires in Africa than from regional fires at certain times.

Adjustments to the law of the wall above an Amazon Forest explained by a spectral link
In a new study, Luca Mortarini and his colleagues introduce a novel approach to the study of the roughness sublayer, using a cospectral budget model. Its originality lies in not considering the mixing layer analogy to parameterize the turbulence statistics. In addition, it relates them to the different scales of the wind velocity spectrum without making any assumption on the property of the flow.
Abundance of pinic acid in its two mirror forms
In a new study, Denis Leppla, Thorsten Hoffmann and their colleagues looked at pinic acid and its chiral forms. Pinic acid forms in the atmosphere through SAO formation from α-pinenes. The team wanted to find out how the chemical reactions in the atmosphere affect the chirality of its product pinic acid.
Limited dispersal of giant bioaerosol particles
The team around Cybelli Barbosa analyzed and studied the distribution patterns of giant bioaerosol particles in the Amazon. For this, they looked at over 500 000 individual particles from five years and eight intensive campaigns and made some exciting discoveries, now published in npj Climate and Atmospheric Science.
Life is in the air
Bioaerosols influence the dynamics of the biosphere underneath. In a new study, Sylvia Mota de Oliveira and her colleagues used the ATTO site to collect air samples at 300 m above the forest. Then, they used DNA sequencing to analyze the biological components that were present and figure out what species of plant or fungi they belong to. One of the most striking new insights is the stark contrast between the species composition in the near-pristine Amazonian atmosphere compared to urban areas.
