Hygroscopic Properties of Atmospheric Aerosol Particles in Various Environments
Atmospheric aerosol particles affect our living environment in many ways. Their effects are influenced by the interaction between the aerosol particles and the ubiquitous water vapour. The number-size distribution is a primary important parameter for aerosol particles and can be measured using the d...

Atmospheric aerosol particles affect our living environment in many ways. Their effects are influenced by the interaction between the aerosol particles and the ubiquitous water vapour. The number-size distribution is a primary important parameter for aerosol particles and can be measured using the differential mobility particle sizer (DMPS). Programs have been developed to invert DMPS measurement data to actual aerosol number-size distributions and further fit it to multimodal lognormal distributions. The hygroscopic tandem differential mobility analyser (H-TDMA) is the essential instrument used in studying aerosol hygroscopic properties. The H-TDMA has been developed continuously regarding measurement control and data acquisition system, as well as in the subsequent data interpretation and quality assurance. Four field experiments have been performed in this work in order to study hygroscopic properties of atmospheric aerosol particles. In a polluted continental environment, the aerosol hygroscopic growth was observed in connection with a ground-based cloud experiment at Great Dun Fell, in northern England in 1995.
