Investigation of molar volume and surfactant characteristics of water-soluble organic compounds in biomass burning aerosol

In this study, we characterize the CCN activity of the water-soluble organics in biomass burning aerosol. The aerosol after collection upon filters is dissolved in water using sonication. Hydrophobic and hydrophilic components are fractionated from a portion of the original sample using solid phase extraction, and subsequently desalted. The surface tension and CCN activity of these different sa...

The density of humic acids and humic like substances (HULIS) from fresh and aged wood burning and pollution aerosol particles

Atmospheric aerosols play significant roles in climatic related phenomena. Size, density and shape of particles affect their fluid-dynamic parameters which in turn dictate their transport and lifecycle. Moreover, density and shape are also related to particles’ optical properties, influencing their regional and global radiative effects. In the present study we have measured and compared the eff...

Optical properties of humic - like substances ( HULIS ) in biomass - burning aerosols

We present here the optical properties of humiclike substances (HULIS) isolated from the fine fraction of biomass-burning aerosol collected in the Amazon basin during the LBA-SMOCC (Large scale Biosphere atmosphere experiment in Amazonia – SMOke aerosols, Clouds, rainfall and Climate) experiment in September 2002. From the isolated HULIS, aerosol particles were generated and their scattering an...
