Land surface phenology from remote sensing

Phenology is nature’s calendar, and changes in phenology are among the most sensitive biological responses to climate change. Across the world, many spring phenological events are occurring earlier, and fall events are happening later, than they did in the past. Land surface phenology is the seasonal pattern of variation in vegetated land surfaces observed from remote sensing.

In this project, we assess the potential uncertainties and errors in detecting land surface phenology using current remote sensing vegetation indexes, such as the AVHRR (Advanced Very High Resolution Radiometer) NDVI (Normalized Difference Vegetation Index) across the Northern Hemisphere (Wang et al. 2017a). The novel method helps to remove snow melting-induced fluctuation for vegetation phenology monitoring (Wang et al. 2017b).
