Xiao, XM (2006). Light absorption by leaf chlorophyll and maximum light use efficiency. IEEE TRANSACTIONS ON GEOSCIENCE AND REMOTE SENSING, 44(7), 1933-1935.
The MODIS Land Science Team has produced a standard product of gross primary production (GPP) for the global land biosphere, using a satellite-based Production Efficiency Model. In this special issue for the validation studies, two papers have examined the accuracy, error, and uncertainty of the GPP product. Here, we present a user's perspective on accuracy assessment of the data products and discuss two large sources of uncertainty in the context of model variables and parameters: 1) light absorption by chlorophyll versus light absorption by canopy and 2) maximum light use efficiency.
