Global Atmospheric Chemistry Section

We develop techniques for measuring and modeling trace gases and aerosols of atmospheric importance, make laboratory experiments to reveal the formation and reaction mechanisms, observe spatial and temporal variations using ground-based, ship, aircraft, and satellite platforms, and simulate emissions, transport, transformation, and deposition processes. Through these activities, we can understand the physical and chemical processes of the troposphere and the stratosphere and the exchange between the atmosphere and the ocean and land surfaces, and analyze their linkages to global air pollution and climate change. We also brief policy implications of the scientific results obtained, aiming to contribute to Japan's and/or international climate and environmental policies that support the goals of global sustainability.
