| Outline of Final Research Achievements |
Strong representation of Solar-Induced Fluorescence (SIF) for the ecosystem-level photosynthesis activity has been confirmed by satellite studies. To examine the potential contribution of SIF emission from lower part of tree ecosystem to total ecosystem SIF emission, the downward SIF from tree canopy and upward SIF from understory were
calculated from the spectrum data in a cool temperate forest in in central Japan (36°08′N, 137°25′E, 1420 m a.s.l.) as well as the upward SIF from canopy top, and the fractional ratios among them are compared on half-hourly and daily bases. We also have conducted the new measurement of SIF by high resolution spectroradiometer at multiple height (0, 8, 14, 18m).
