Codominant water control on global interannual variability and trends in land surface phenology and greenness
Abstract Identifying the relative importance of climatic and other environmental controls on the interannual variability and trends in global land surface phenology and greenness is challenging. Firstly, quantifications of land surface phenology and greenness dynamics are impaired by differences bet...
