Working Group: Basic Aerosol Processes (BAP)
WG Chair: Jonas Elm
The lack of fundamental understanding of the processes that govern aerosol formation and growth causes tremendous uncertainties in the predictions of macroscopic aerosol behaviour, such as nanoparticle characteristics, optical properties, aerosol-cloud interactions, and the effect of atmospheric aerosols on global climate estimations. These uncertainties in aerosol chemistry and dynamics may be addressed by modelling and/or simulations at various length and time scales from the atomistic (quantum chemistry, molecular dynamics) all the way up to the continuum level (computational fluid dynamics, population balance equations). The basic aerosol processes working group is targeting these processes as well as focusing on a broader fundamental understanding of aerosol properties and dynamics that would have impact in other areas such as aerosol technology. The topic 5 work group comprises three main subjects, that all target basic aerosol processes:
Aerosol chemistry: Fundamental investigations in aerosol chemistry (theoretical and experimental). Chamber and flow-tube studies looking into oxidation processes of both anthropogenic and biogenic volatile organic compounds. Also includes gas-phase kinetic studies of aerosol precursors.
Aerosol modelling: All aspects of the numerical modelling of basic aerosol processes, including regional and global transport models, numerical computation of particle transport in fluids, quantum chemical calculations and molecular dynamics simulations.
Aerosol physics: Fundamental investigations of aerosol dynamics, aerosol filtration, interactions between aerosols and surfaces, nucleation and growth, agglomeration and fragmentation (theoretical and experimental). Also includes studies of fundamental material properties of aerosols such as electromagnetic and optical behaviour.
The BAP working group welcome all contributions to basic aerosol science that relate to aerosol physics and chemistry, modelling, simulations and fundamental research into aerosol and material properties.
