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...
This paper explores the potential of using the Medium Resolution Medium Spectrometer (MERIS) Terrestrial Chlorophyll Index (MTCI) for estimating gross primary productivity across a range of vegetation cover types. Correlations between flux tower measures of GPP and corresponding MTCI for years between 2003 and 2007 were established for 30 sites across the Americas. Correlations were seen to range...
