A prominent issue with the state of current terrestrial
biosphere models pertains to unrealistic parameterizations
of model parameters in space and time. Key biochemical
controls on carbon uptake by vegetation canopies are
typically assigned fixed literature-based values for broad
categories of vegetation types despite the fact that these are
affected by a complex interplay of environmental and
physiological factors, which inevitable leads to significant
temporal and spatial variability. Considering the high spatial and temporal resolution of current satellite
constellations, candidate remote sensing techniques should
play a key role in advancing model parameterizations and
ultimately improve estimations of gas and energy fluxes in
terrestrial ecosystems. This study investigates the utility of
remote sensing based retrievals of leaf chlorophyll for
estimating leaf photosynthetic capacity (i.e. Vcmax) and for
constraining model simulations of gross primary
productivity (GPP).
