Title

Sources and sinks of aerosols over the Amazon Basin

Abstract

Several new observational studies (Andreae et al., 2018) suggest a high (up to 10 000 per squared cm) number concentration of fine-size aerosol particles in the upper troposphere. Such a huge amount cannot be explained with simple transport from boundary layer and is attributed to the process of in-situ formation from gaseous precursors. The elevated amount of larger particles ( > 90 nm) was also observed in the upper troposphere. They consisted mostly of organic matter and nitrate and formed efficient CCN.
These observations can lead to a better understanding of the aerosol burden as well as understand deep convective clouds as transporters of aerosols both upwards and downwards.
