Site-specific apparent optimum air temperature for vegetation photosynthesis across the globe.

ABSTRACT: The apparent optimum air temperature for vegetation photosynthesis (T_opt) is a key temperature parameter in terrestrial ecosystem models estimating daily photosynthesis or gross primary production (GPP, g C/m²/day). To date, most models use biome-specific T_opt (T_opt-biome) parameter values. Given vegetation acclimation and adaptation to local climate, site-specific T_opt (T_opt-site) is needed to reduce uncertainties in estimating daily GPP across the scales from site to region and the globe. Previous studies have demonstrated using the Enhanced Vegetation Index (EVI) derived from Moderate Resolution Imaging Spectroradiometer (MODIS) images and daytime air temperature data to estimate the T_opt-site at the eddy covar
