| Outline of Final Research Achievements |
To provide data-oriented global estimates of soil greenhouse gas fluxes, I conducted modeling using data obtained worldwide. First, I applied a regional, simple soil greenhouse gas flux model (SGR), which is based on data observed all over Japan, and estimated global soil carbon dioxide emission, methane uptake, and nitrous oxide emission fluxes. Second, I developed models based on global databases of soil carbon dioxide flux and nitrous oxide flux, and applied the models globally. The global total fluxes, spatiotemporal distributions, and seasonality were examined.
