The terrestrial ecosystem can absorb about 30％ of the anthropogenic carbon emissions through vegetation photosynthesis,which plays an important role in the global carbon cycle and slowing the rise of atmospheric carbon dioxide concentration.The solar-induced chlorophyll fluorescence (SIF) remote sensing technology developed in the last 10 years can monitor the actual photosynthesis of vegetation,providing new ideas and methods for the study of global terrestrial ecosystem carbon cycle.This paper reviews the recent progresses in the study of satellite-based SIF observations and their applications in terrestrial ecosystem carbon cycling and land-atmosphere interaction,especially in the estimation of global vegetation gross primary productivity and the development of terrestrial ecosystem carbon cycle models,and further discusses the challenges faced by research in this field and the future development directions.
