Atmospheric and Thermal Environmental Engineering

Environmental issues should be discussed by considering mutual effects among social activities, environmental and ecological impacts. Consumption of natural resources and energy causes climate change through their emissions of greenhouse gases, damages on ecosystem, decrease of agricultural productions, and natural disasters. These effects can only be foreseen through comprehensive analysis of social and environmental systems. The main esearch area of this chair is on the development of integrated assessment modeling by coupling social models hich cover economy, industry, household, and physical models which include atmospheric transport and land surface water hydrological circulation in order to forecast global environmental problems including global warming, atmospheric pollution, and so on.

Research Topics

We conduct researches mainly on climate change mitigation, using a computer simulation model called “Integrated assessment model” that integrates relevant discipline such as energy, economy, agriculture, land use, and water use into a single platform. We primarily focus on future greenhouse gas emissions, their reduction measures, and economic implications of such climate mitigation policies. Meanwhile, the economic analysis of climate change impacts is also one of the scopes of our studies. Moreover, beyond the climate change issue, to provide solutions to achieve broader sense of sustainable development is the newly focused area in the research arena. We cover multi-scale areas spatially temporally. For instance, spatial resolution varies from national (each country of Asia), whole Asia, to the globe and sometimes gridded scale analysis is also carried out (0.5 °x0.5 °). The temporally coverage is near to long-term future such as next decade to entire this century.

Research Topics

The integrated environmental assessment model

Socio-economic activity emits substances such as carbon dioxide, sulfurous acid gas and particulates into our atmosphere, with an associated environmental impact at both the local and global levels. Reducing the damage caused by these substances requires a comprehensive approach that takes into account social phenomena such as urbanization, economic progress and energy consumption together with environmental phenomena such as pollutant emissions and their environmental impact.  We develop integrated assessment models, called the Asia-Pacific Integrated Model (AIM), as important tools for the development of countermeasures to these problems.

Material flow and stock analysis and development of mitigation countermeasures for environmental impacts

Our research into the environmental impact of industry and household involves identifying the underlying mechanisms and developing appropriate countermeasures via numerical modeling in three main areas:

  1. Trends in resource usage, waste generation and energy consumption in the industrial and household sectors;
  2. key technologies for reducing resource usage, waste generation and energy consumption; and
  3. correlations between these initiatives and the macro economy.

The numerical models thus developed are used in the development of environmental countermeasures and evaluation of environmental technologies.

 Simulation of the global transport of atmospheric pollutants and the social and human impact of environmental changes

Emissions of atmospheric pollutants not only cause pollution in the vicinity of the emission source, it also impacts on the neighboring countries and, in some cases, the worldwide. The Matsuoka Laboratory is using computer simulations based on socio-economic databases and geographical data systems to investigate key issues such as: transport of pollutants with respect to factors such as atmospheric circulation, precipitation and chemical reaction; assessment of the economic and health impact of pollution; and strategies to reduce emissions and mitigate the associated damages. Simulations are used to perform quantitative analysis of emissions of pollutants and its transport and transformation in the regional and continental scale, and to generate forecasts for use in the preparation of policy scenarios. The figure shows a forecast of dispersion and deposition of sulfur oxide from thermal power plant and factories expected to be operational through to 2020, for the entire Asian region.
