Title: Terrestrial biosphere models may overestimate Arctic CO 2 assimilation if they do not account for decreased quantum yield and convexity at low temperature

Abstract

Here, we measured the effect of temperature on the response of photosynthesis to irradiance in six Arctic plant species and determined the quantum yield of CO 2 fixation (Φ CO2) and the convexity factor (θ). We also determined leaf absorptance (α) from measured reflectance to calculate Φ CO2 on an absorbed light basis (Φ CO2.a) and enable comparison with nine TBMs.
