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

这个项目的目的是突出地表和表面的互动various vegetation, especially forests. In order to accomplish this purpose，观察与建模studies were made in the project.At first，观察水，能量与二氧化碳D22 fluxes above the forest canopies包括various environmental factors such as air temperature， humidity, wind velocitysoil moisture, soil temperature，CO - 22 - D2 concentrations were investigated in two sites. One是broad-leaved deciduousforest located at the University forest of Tokyo University of Agriculture and Technology in TochigiOshiba Kogen in Nagano Prefecture. based on these other was The larch forest at Oshiba Kogenobservations,the effects of forests on fluxes above . Models were developed for estimating fluxeswithin forest canopy。

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.
