Scientists revealed shifting spring phenology of Arctic tundra with satellite and ground observation

Phenology, the seasonal and interannual dynamics of vegetation, is recognized as an important indicator of ecosystem response to climate change. With stronger warming trend at higher latitudes, the seasonality of vulnerable Arctic tundra is more sensitive. Now researchers in China have investigated the temporal and spatial variations of the spring phenology using multiple remote sensing indices and ground observations, explored the significance and feasibility of different methods applied to different data sources.
