| Research Abstract |
Long-term micrometeorological and turbulent flux observations were made in an apple orchard, and daily evapotranspiration was determined using three different methods. The estimation methods for canopy heat storage and snowmelt latent heat were also proposed and introduced in the calculation process of the evapotranspiration. As a result, precise estimation of evapotranspiration based on the monthly crop coefficient has become possible, although the estimation of soil water content remained unsolved. Furthermore, estimation methods for solar radiation and evapotranspiration using satellite data were proposed, which will lead to the wide area estimation of evapotranspiration rate.
