Outline of Final Research Achievements |
In this study, we developed a new three dimensional sun-induced chlorophyll fluorescence emission model. The three dimensional forest structure information was collected by the terrestrial LiDAR measurements of the trees in the field site. The collected data were used as input data of the developed model. With this newly developed model, the simulated global patterns of sun-induced chlorophyll fluorescence were evaluated. This study also quantified the applicability and limit of the developed model. Satellite measurement of the global sun-induced chlorophyll fluorescence is one of the upcoming and encouraging variables to make better understanding in the global terrestrial photosynthesis estimation. The new model will contribute to the improved understanding of the relationship between satellite-based sun-induced chlorophyll fluorescence measurements and leaf- and canopy-scale photosynthesis.
