Solar-induced chlorophyll fluorescence (SIF) has been considered a direct proxy in monitoring vegetation actual photosynthesis. However, applications in the Earth science have been greatly limited due to challenges in use of remotely sensed SIF. This is because the linkage between vegetation actual photosynthesis and SIF retrieved from the canopy reflected radiance exists numerous uncertainties. It...
In-depth study of the soil moisture mechanisms and understanding of the soil moisture transport law has an important practical significance for regional water resources management and the challenge of the water resources scarcity. Using traditional methods of soil moisture monitoring, deep soil layers can be monitored, but continuous monitoring of soil moisture at the regional level cannot be achieved...
Multi-sensor NDVI(Normal Different Vegetation Index) continuity is very important in long-term earth observation and climate research. Correlation coefficient is chosen to analyse the continuity of NDVI between medium resolution satellites: Beijing-1, TM(LandSat-5), SPOT-4. After the selection of sample pixels(remove pixels that contain water and great topographic area), results shows that Beijing-1...
