Message

I use remote sensing as an observational tool to conduct research into the diagnosis of the current state of global environments. I intend, however, to use the opportunity presented by this GCOE program to forge collaborations with people working in treatment-based disciplines. There are three departments from the Graduate School of Environmental Studies taking part in this program, along with one department from the Graduate School of Bioagricultural Studies; this means I will be working with faculties and students from diverse disciplines with diverse research interests. I am looking forward to exchanging ideas with them all. Geologists are normally to be found out in the field, so I am equally looking forward to visiting the actual sites of environmental problems and seeing them with my own eyes. I hope to pursue my research through a combination of observations over a wide area through remote sensing and field-based survey.

Research Themes

Elucidation of Carbon Cycles in Terrestrial Ecosystems

I use wide-range observation via satellite remote sensing and ecosystem modeling to analyze the carbon dioxide absorption of terrestrial ecosystems and their impact on global warming. The figure shows fluctuations in net primary production since the 1980s, and further shows an upward throughout the entire globe (warm colours).

Analysis of Remote Sensing Data such as Terra/ASTER, Kaguya/LRS

Using data from the ASTER instrument on NASA's Terra satellite, I estimate evapotranspiration levels in vegetated regions, heat balance analysis in urban centers, and geological mapping. I also use data from a lunar radar sounder onboard the Kaguya lunar probe, to analysis the subsurface structure of the moon, and I am also working towards clarifying the thermal history of the moon.
