Outline of Final Research Achievements

To develop the satellite remote-sensing in evergreen and deciduous broad-leaved forests, we performed long-term continuos phenological observations by near-surface remote-sensing techniques in ecosystem sites in Borneo and Japan. Based on the ground-truthing obtained from our field studies, we accurately detected the spatio-temporal variability of vegetation in Borneo and Japan by analyzing the satellite-observed daily vegetation index data. In consequence, we identified that (1) usability of phenological observations by using digital cameras, (2) uncertainties of remote-sensing observations in a leaf-fall period, (3) characteristics of spatio-temporal variability of the timing of leaf-flush and leaf-fall in Japan, and (4) year-to-year variability of land cover changes by human activities in Borneo.
