Atmospheric Chemistry - Mikinori Kuwata

Overview

We investigate atmospheric chemistry of tropical Asia, which plays important roles for both the global climate and local air quality. We also work on developing new tools to improve our understanding on atmospheric chemistry.

Atmospheric chemists try to understand emission, atmospheric processes, deposition, and environmental impacts of atmospheric chemical species. Because of its nature, atmospheric chemistry is an interdisciplinary research area, which involves chemistry, physics, atmospheric and oceanic sciences, aerosol science, agricultural science, and others.

Tropical Asia is an important and a unique place for atmospheric chemistry. For instance, wildfire in tropical Asian countries is one of the globally important sources of CO2. It is also a dominant source of particulate matter in this region, which affects air quality.

Another example is emission of trace gas species from forests. Tropical rain forest is the most important source of some important volatile organic compounds such as isoprene. However, replacement of tropical rain forest by plantations is possibly changing atmospheric chemistry of this region. Importance of those scientific research topics have been recognized, but rarely investigated. Therefore, it is still difficult to reproduce atmospheric chemistry in this important region even if we use state of the art three-dimensional numerical models. Our goal is to provide a better scientific understanding on those phenomena.

Development of research tools such as instruments and data analysis procedures is critical for this research area. Therefore, we continuously work on innovating and improving techniques for our research.

Latest Projects

This project will provide a systematic understanding on haze in equatorial Asia with a combination of atmospheric observation at NTU campus and laboratory experiments, eventually allowing atmospheric chemists to simulate haze more accurately.

Peat found at Riau Province, Sumatra.

This project will be the first to continuously monitor haze at its source in Indonesia and will provide a jumping-off point to investigate the impacts of haze on local and global environments.
