Computer simulation is an important tool for investigating the global environment and predicting its future state. Our research group has been developing numerical models simulating atmospheric phenomena at scales varying from regional to global. Observation and data analysis are also important part of our research. Our mission is to understand the atmospheric environment comprehensively through the combination of observations and computer simulations. We emphasis on the following research themes;
– Numerical simulations of greenhouse gases such as carbon dioxide and methane, and source/sink inversion analyses of gases using chemical transport models.
– Development of new satellite sensors and algorithms for analyzing satellite data to study the atmospheric environment and greenhouse gases.
– Field experiments of greenhouse gas measurements using aircraft and ground-based measurement systems ( Joint researches with Russia and India).
– Studies of Earth water cycle system with stable water isotopic information
– Terrestrial water and energy cycles with land surface and hydrological models
– Regional climate prediction with dynamical downscaling technique
– Reconstruction of past several thousand years with data assimilation techniques
