Aerosol technology includes the research and development fields ranging from conventional areas such as emission control, filtration and powder technology, to more recent ones such as advances in functional nanomaterials and Industry4.0 systems. Specific sub-topics could be but are not limited to: Material synthesis and structuring via aerosol/gas phase processes. Functional nanomaterials, e.g. coating and surface modification of nanoparticles. Nanostructured materials from aerosols including also films and coatings by aerosol deposition. Scaling-up: from lab-scale to industrial production via aerosol processing. Filtration and gas cleaning technologies. Electrical Phenomena. Charging and electrical effects. Electrosprays. Industrial and high temperature aerosols. Combustion aerosols and related emission control e.g. in the transport and energy sector.
Ambient aerosols are recognized to have important impacts on the ecosystem, human health and climate change. However, aerosol formation and aging mechanisms, as well as a number of related atmospheric processes are not well understood. Of our main interest are physical, chemical, and optical properties of ambient aerosols and their mimics, including time-resolved investigations of the complex multiphase system and aerosol modelling. We aim to provide better insight, new aspects and knowledge on the lifecycle of atmospheric aerosol particles, with an emphasis on their roles in cloud formation and Earth’s radiative balance.
The Atmospheric Aerosol Studies working group is an interdisciplinary scientific forum that strives for the scientific exchange and the highest-level scientific discussions within the wide atmospheric aerosol science community. We warmly welcome contributions from field as well as aerosol chamber, laboratory, and modelling studies considering any aspect of atmospheric aerosols and their processing.
The Topic of Aerosol Measurement Techniques covers all aspects related to the measurement of aerosol and their properties and the evaluation of the resulting data. These techniques cover a very wide range of applications, including atmospheric, workplace, and process aerosols. The main topics are:
Sampling and measurement of aerosols. This includes both ambient and workplace environments and issues relating to sampling strategies, selection of sites, sampling artifacts, development and improvement of sampling techniques as well as physical and chemical analysis.
Development of new measurement approaches. This includes, but is not limited to, new approaches and applications of optical techniques, aerosol sizing and other physical parameters, chemical composition and the miniaturization of aerosol sensors.
Data analysis techniques. Issues relating to the interpretation of aerosol measurements such as source apportionment, relationship to other measurements such as gaseous and meteorological parameters.
Legislation and policy. Application of aerosol measurements to the regulatory framework such as the measurement of limit values, methodologies connected to demonstration of natural contribution to PM burden – e.g. sea salt, dust episodes, natural organic emissions.
Atmospheric science. The innovative use of existing instrumentation or the application of new instrumentation to study new or established issues in aerosol science.
Many aerosols lead to adverse health effects while others have therapeutic uses; thus aerosols and health are closely linked. Understanding the relationships between exposure and effects is key to understanding and mitigating health impacts. In this theme we invite contributions related but not limited to:
- Exposure sources, levels and assessment techniques
- Respiratory tract processes
- Microenvironments in indoors and at workplaces
- Health-relevant aerosol characteristics
- Health responses from toxicology to epidemiology
See detailed abstract topics for more keywords. The Working Group warmly promotes and facilitates interdisciplinary communications to exchange information in diverse fields such as physics, chemistry, medicine, biology, pharmacy, toxicology, epidemiology, exposure science, engineering, and others.
The lack of fundamental understanding of the processes that govern aerosol formation and growth causes tremendous uncertainties in the predictions of macroscopic aerosol behavior, 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 flowtube 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.
