Sessions
“One atmosphere in Asia-Pacific region – multi-scales, multi-interactions, and multi-effects –“.
To achieve this goal, we will open the following sessions.
Sessions planned for the CMAS-Asia-Pacific Conference
- Ozone and PM2.5 pollution in Asia-Pacific region
- Updating of air quality modeling
- Multi-scale modeling applications and evaluation
- Emission inventory
- Linkage between air quality and climate
- Multi-effects and policy making
Ozone and PM2.5 pollution in Asia-Pacific region
Due to the intense anthropogenic emissions, the air quality status in the Asia-Pacific region has been paid attention. Nowadays, anthropogenic emissions showed dramatical changes, and we need to understand the past, current, and future status of air pollution, especially for the secondary species of photochemical ozone and particulate matter (PM2.5). This session will invite various topics for not only model application but also monitoring. The fusion of them is also welcomed.
- Air quality model application
- Air quality sensing and monitoring
- Linkage and fusion between modeling and monitoring
Updating of air quality modeling
Work in recent years has vastly improved the science of air quality and methodologies for modeling and analyzing the distribution of air pollutants at various temporal and spatial scales. We also include discussing here the potential usages/applications of Machine Learning (ML). In addition, recent advances have enabled the use of cloud computing for atmospheric model applications. The use of cloud computing avoids the use of in-house resources and the associated costs of maintenance. The topics for this session will include:
- Progress of numerical schemes
- Machine learning
- Cloud computing
Multi-scale modeling applications and evaluation
Both observations and modeling studies have demonstrated the long-range inter-continental transport of pollutants. The impacts of long-range pollutant transport on background pollutant levels in another region may then impact the attainment of local air quality standards. Additionally, increased concerns about climate impacts on regional and local ecosystem disciplines have driven the need to utilize outputs from global models in regional modeling systems with different temporal and spatial scales. This session seeks the key issues related to the consistent coupling of atmospheric physical and chemical processes on local-to-global scales and related modeling applications. Topics of interest in this session include:
- Global to regional scale modeling
- Street and neighborhood scale air quality study
Emission inventory
This session is dedicated to the application of innovative methodologies for preparing and processing bottom-up emissions of air quality modeling systems. Techniques to improve estimates of dust, biogenic and wildfires and emissions, and temporal allocation of anthropogenic sources are of special interest for this session. The approach of top-down estimates is also of particular interest. Session topics include:
- Bottom-up emission inventory
- I/SVOC emission
- Inverse modeling
Linkage between air quality and climate
The emissions of air pollutants, short-lived climate forcers (SLCFs), and greenhouse gases are closely related to the energy system. Understanding how the energy system may evolve in the future and the resulting implications on the environment is critical if environmental decision-makers are to address these challenges proactively and efficiently. The goal of this session is to highlight research efforts involved in exploring the linkage between air quality and climate. Among the topics that are appropriate for inclusion are:
- Interaction between air quality and climate
- Integrated assessment for future energy, climate, and air quality strategies
Multi-effects and policy making
Air quality models continue to be important tools for guiding decision-makers in preparing emission regulation strategy applications to set standards for compliance. In addition, the current COVID-19 pandemic that is affecting the entire planet had periods of a shutdown at different times in several parts of the world and this led to emissions reductions. This unprecedented event might be the clue for future emission regulation pathways. We seek presentations that describe how air quality models are used in specific applications. This session's topics include:
- COVID-19 and air quality
- Modeling and their application for ecosystem impact and/or epidemiology
- Modeling and policy making
