This research describes the seasonal phenological pattern of Africa's vegetation and its recent trends using MODIS EVI time-series data with a relatively fine spatial resolution of 500 m and a long temporal range of 15 years (2001–2015). The objectives were to measure the vegetation phenology of the major land cover types and determine the temporal trends across the geographical sub-regions of Africa...
Terrestrial chlorophyll content is a key environmental variable that is difficult to estimate accurately using remotely sensed data. Some of the pioneering studies in this field were undertaken by Kirill Kondratyev and co-workers in the 1970s and early 1980s. These studies paved the way for the operational global chlorophyll content maps of today. This chapter reviews some of Kondratyev’s pioneering...
Envisat's Medium Resolution Imaging Spectrometer (MERIS) acquired multi-spectral imagery of the Earth in the optical domain over terrestrial surfaces for a decade at global scale. For the last ten years, scientists have used multi-spectral data or terrestrial geophysical products for characterizing the state of the global system and its variability. Our paper shows highlights of several achievements...
