Atmospheric and Environmental Sciences Section mainly focuses on the spatial-temporal variations of atmospheric trace gases and ice clouds in the troposphere and stratosphere and on the dynamical coupling processes between stratosphere and troposphere in the tropics by using the global data from the satellite observation. In addition, we research on the development of analysis algorithm methods of greenhouse gases and ice clouds by the spectral data from satellite observation and small satellite project research on observation of ice clouds and water vapor.

1. Elucidation of dynamical interaction processes between troposphere and stratosphere in the tropics through data analyses of trace gases and clouds
2. Development and improvement of retrieval methods for greenhouse gases and clouds from satellite observations
3. Study on the spatial and temporal variations of greenhouse gases, e.g., CO₂, CH₄, H₂O, O₃, in the troposphere and stratosphere
