Response of vegetation to drought across global land biomes

Understanding the dominant time-scales at which drought most influences vegetation might help assessing the resistance and resilience of vegetation and improving our knowledge of vegetation vulnerability to climate change. In our article recently published in Proceedings of the National Academy of Sciences we evaluated the response of the Earth land biomes to drought by correlating […]

Article: Temporal evolution of vegetation activity by multitemporal Landsat imagery

We analyzed the temporal evolution of vegetation activity on various land cover classes in the Spanish Pyrenees for the period 1984 to 2007. Two time series of the normalized difference vegetation index (NDVI) were used, corresponding to March (early spring) and August (end of summer). The series were generated from Landsat TM and Landsat ETM+ images, […]
