[ACG40-P06] Relationship in anomalous changes in solar-induced chlorophyll fluorescence to the environmental factors for last 10 years
Keywords:Satellite data, Climatic fluctuation, carbon cycle
High correlations between SIF and both NDVI and inversed land Carbon flux emerged in Australia, Middle of North America, S&W of Africa, NW India, which correspond to grass & shrub lands. This suggests that the photosynthesis in drier and less productive ecosystems showed directly positive reactions to leaf biomass change increase probably due to simple canopy structure.
In terms of teleconnection indices, the relationships between the globally averaged values were unclear overall. Specifically, the SIF anomaly showed clearly positive and negative responses to both Tsurface and NiNO3 anomalies in northern and southern hemispheres, respectively, on contrary to unclear globally positive response to Precipitation’s one
