The phytoplankton pigment absorption $(a_{{\rm{ph}}})$-based productivity model (AbPM) is commonly used to estimate marine net primary production (NPP). In the AbPM, $a_{{\rm{ph}}}$ is used as the key predictor of phytoplankton photosynthetic efficiency. Previous studies have shown that the size of phytoplankton could affect the photosynthetic efficiency. Thus, a size-fractionated AbPM was proposed...
Accurate estimation of CO2 fluxes is significant for studying the interaction between the terrestrial biosphere and the atmosphere, which is also highly relevant to the climate-policy making. Gross primary productivity (GPP), defined as the overall rate of fixation of carbon through the process of vegetation photosynthesis, is the total influx of carbon into an ecosystem. Many remote sensing approaches...
Qinghai-Tibetan Plateau plays an important role in estimating net primary productivity of grassland ecosystem for global carbon cycling research. In this paper, boreal ecosystem productivity simulator (BEPS) model was modified according to the characteristics of grassland canopy. A hypothesis of horizontal homogeneity and vertical layer was put forward for grassland canopy and BEPS was modified to...
