Terrestrial ecosystem models explained by laws of ecophysics can evaluate the terrestrial ecosystem functions from plot to globe. However, such models depend on the quality of input data such as the land cover and LAI. Therefore, we should improve them to gain high-quality and accurate output data such as GPP. To do so, satellite remote sensing is useful because it can observe the land surface widely with high spatio-temporal resolution. However, we should give a sufficient ecophysiologocal interpretation to the satellite-observed reflectance or radiance because they don't show the ecophysiological phenomena directly. We should also evaluate the influence of cloud contamination fully because the visible spectroradiometer onboard satellite can not remove them. To solve these problems, we should check the quality of satellite data by the ground-truthing. We made the following three goals; (1) We develop the comprehensive ground observation network, which connects satellite data and terrestrial vegetation information. (2) We clarify the relationship between satellite data and ecophysiological phenomena. (3) We check the satellite-based LAI by the ground-truthing. In this presentation, we state the results of these goals as the campaign “Satellite Ecology” (the 21st Century COE program at Gifu University) at Takayama super site in Japan, which belongs to AsiaFlux network.
