Therefore, enhanced aerosol emissions due to human activity in the Amazon Basin may have a stronger impact on climate than emissions in other continental regions. In spite of the large organic fraction in the Amazonian aerosol, a detailed analysis of number distributions and size‐dependent chemical composition indicates that sulfate plays an important role in CCN activity.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1381699996485552386","@type":"Researcher","foaf:name":[{"@value":"Gregory C.
