| Outline of Final Research Achievements |
I developed an evaluation method of spatial-temporal uncertainty for turbulence measurements. Furthermore, I developed new evaluation method for partitioning Evapotranspiration/CO2 fluxes into evaporation/transpiration and photosynthesis/soil respiration. I clarified that CO2 flux and H2O flux in the dry season were not often possible of Monin-Obukhov similarity due to the plant physiological heterogeneity and soil surface water heterogeneity.
