Outline of Final Research Achievements

With this research project, the 3-D modeling of Martian material transport using a general circulation model (GCM), especially the water cycle, HDO/H2O isotopic fractionation and CO2 ice snowfall related to the formation of seasonal ice cap, has largely progressed. Now the development of a GCM which will be a basement of the studies of Martian material transport collaborating with various observational data has mostly completed. Parts of the research accomplishments collaborating with observations have publishes as papers. Especially the paper about the simulation of CO2 snowfall and seasonal ice cap formations in northern winter polar region was highlighted by Nature Geoscience, and became an outstanding work. Also the first study of the generation of propagation of Martian gravity waves with a high-resolution GCM has been done.
