Mapping Crop Phenology in Near Real-Time Using Satellite Remote Sensing: Challenges and Opportunities

Figure 1

A scheme for monitoring phenology in near real-time and short-term forecasting from timely available satellite observations for (a) spring vegetation growing phase and (b) autumn senescence phase. The red circles are the VI data available at the time of simulating the temporal trajectories. The black bar represents the potential range of VI values at the climatological phenology timing. The trajectories are calculated from the available observations and the climatological VI. The curves are potential trajectories varying with the standard deviation in climatology (modified from Zhang [46]).
