Description
Summary:	We illustrate functionality and performances of the oscillating bubble tensiometer, used for studying the influence of atmospheric organic carbon on the interfacial properties of clouds and aerosols. We report experimental observations of the responses of dynamic surface tension consequent to harmonic disturbances of surface area, for samples of cloud-water and of aerosol dissolved in water. The oscillating-air-bubble tensiometer appears a suitable instrument for the assessment of the ‘availability to the air–water interface’ of natural and man-made adsorption-film-forming organic materials, present in the atmosphere.
