Observation and Modeling on Water, Energy and CO2 fluxes above Forests

这个项目的目的是通过各种迁移、特别是森林来澄清陆地表面和大气层之间的相互作用。In order to accomplish this purpose， Observational and modeling studies were made in the project.首先，观察水，能源和CO-D22-D2 fluxes over the forest canopies，包括各种环境因素such as air temperature， humidity， wind velocity，土壤湿度，土壤温度， and CO-D22-D2 concentrations were investigated in两个站点。一个是位于东京大学农业和技术大学的广片森林，位于托奇吉地区的东京大学农业和技术。另一个是长野遗址上的奥什巴·科根的云雀森林。根据这些观测，森林对通量的影响是评估的。模型已经开发出来，以估计在森林峡谷上方和在森林峡谷内。

The purpose of this project is to clarify the interaction between Landsurface and Atmosphere through various vegetation, especially forests. In order to accomplish this purpose, observational and modeling studies were made in the project.At first, observations on water, energy and COィイD22ィエD2 fluxes above the forest canopies, including various environmental factors such as air temperature, humidity, wind velocity, soil moisture, soil temperature, and COィイD22ィエD2 concentrations were investigated in two sites. One is the broad-leaved deciduous forest located at the University forest of Tokyo University of Agriculture and Technology in Tochigi Prefecture. The other was the larch forest at Oshiba Kogen in Nagano Prefecture.Based on these observations, the effects of forests on fluxes were evaluated. Models were developed for estimating fluxes above and within forest canopy.
