Forest ecosystem plays an important role in regulating the global climate by serving as the primary carbon pool for atmospheric carbon dioxide. Deforestation and forest degradation could pose a serious threat on the global emission of greenhouse gases, and this has been declared as the critical issue for United Nation's REDD programme. Under the threat of global warming and climate change, it is critical...
Sun-induced fluorescence (SIF) is an electromagnetic signal emitted by the chlorophyll of green leaves which has been shown to be a good proxy for plant photosynthetic activity. Recent developments in spaceborne spectrosopy have led to the derivation of the first global maps of SIF from a number of space-based spectrometers. This contribution will provide an overview on the state-of-the-art of terrestrial...
There is a growing interest in monitoring the gross primary productivity (GPP) of crops due mostly to their carbon sequestration potential. Both within- and between-field variability are important components of crop GPP monitoring, particularly for the estimation of carbon budgets. In this letter, we present a new technique for daytime GPP estimation in maize based on the close and consistent relationship...
