Chemical transformations at aerosol surfaces influence aerosol properties (volatility, radiative, toxicity) and gas-phase composition, but kinetic parameters are often poorly correlated with aerosol properties (e.g. phase, composition, viscosity) or conditions (e.g. RH, T) leading to uncertainty in models.
In this project laboratory studies using (i) an aerosol flow tube equipped with a Potential Aerosol Mass (PAM) chamber and sensitive laser instrumentation and (ii) an aerosol chamber equipped with a Raman spectrometer for determination of diffusion coefficients will be used to correlate measured rates of uptake and production at aerosol surfaces (single component/mixtures, SOA, ambient aerosol) with aerosol properties. A focus will include organic aerosols (varying phase, viscosity).
The laboratory studies will be complemented by modelling using UmanSysProp, an automated online facility for calculating the properties of aerosol particles under experimental or ambient conditions. The rates of heterogeneous uptake, ageing and other parameters can then be calculated for inclusion in atmospheric models.
