Special Issue "Emissions, Transport and Fate of Pollutants in the Atmosphere"
Deadline for manuscript submissions: 15 May 2020.
Interests: atmospheric transport; multiscale atmospheric modeling; turbulence and turbulent flows; planetary boundary layer meteorology; air quality modeling; air pollution; chemical transport models; aerosols emissions and transport; air-surface exchange; atmospheric dust
Air pollutants (including chemicals, pathogens, allergens, and toxics) go through many dynamical, physical, and chemical processes from emissions to deposition. Aerosols and gasses are released from various sources to the atmosphere, where they interact with the planetary boundary layer, radiation, and clouds. The transport and dispersion of pollutants may occur at various spatial and temporal scales before they are deposited back on land or water. There are still many scientific questions concerning multiscale and multiphysics phenomena that govern the emissions, transport, and fate of pollutants in the atmosphere.
This Special Issue is devoted to research that aims to improve our understanding of physical mechanisms controlling emissions, transport, and deposition of airborne pollutants, chemicals, pathogens, allergens, or toxics. We are especially interested in original research articles addressing the multiscale and multiphysics nature of these mechanisms. All theoretical, modeling, and observational studies are welcome. Some topics of interest include, but are not limited to:
- Air-surface exchange of pollutants
- Emissions due to atmosphere and land/water interactions
- Pollutants pathways in the atmosphere
- Long-range transport
- Wet/dry deposition processes

Title: Pollution Transport Patterns Obtained Through Generalized Lagrangian Coherent Structures
Authors: P.J. Nolan, H. Foroutan, and S.D. Ross
Abstract: Identifying atmospheric transport pathways is important to understand the effects of pollutants on weather, climate, and human health. The atmospheric wind field is variable in space and time and contains complex patterns due to turbulent mixing. In such a highly unsteady flow field, it can be challenging to predict material transport over a finite-time interval. Particle trajectories are often used to study how pollutants evolve in the atmosphere. Nevertheless, individual trajectories are sensitive to their initial conditions. Lagrangian Coherent Structures (LCSs) have been shown to form the template of fluid parcel motion in a fluid flow. LCSs can be characterized by special material surfaces that organize the parcel motion into ordered patterns. These key material surfaces form the core of fluid deformation patterns, such as saddle points, tangles, filaments, barriers and pathways. Traditionally the study of LCSs has looked at coherent structures derived from integrating the wind velocity field. It has been assumed that particles in the atmosphere will generally evolve with the wind. Recent work has begun to look at the motion of chemical species, such as water vapor, within atmospheric flows. By calculating the flux associated with a species, a new generalized velocity field can be obtained. This work looks at analyzing coherent structures associated with generalized velocity fields from chemical species in order to find their pathways in the atmosphere.
Title: Investigation of potential source regions of PM in Shenzhen, South China
Author: Jianjun He
Abstract: Understanding the potential source areas of pollutant is the key to scientific prevention and control of atmospheric pollution. Using mesoscale meteorological model WRF, atmospheric diffusion model FLEXPART, and pollutant emission inventory, this study investigated the potential source areas of PM2.5 in Shenzhen during 2013 to 2017 by combining the contribution of air mass and emission inventory. WRF can well reproduce meteorological fields in Shenzhen and surrounding areas, which is very important for the accuracy of potential source areas. Eight major backward trajectories were determined by cluster analysis. The contribution rates of local and surrounding cities to receptor (Shenzhen urban) were calculated. Atmospheric circulation was classified by an objective weather classification method. The difference of the potential source areas in different seasons and different atmospheric circulation types were also provided. The research results will help to deepen the understanding of the causes of air pollution in Shenzhen.
