This spreadsheet contains plant species' photosynthetic data on carboxylation (Vc,max) and electron transport rate (Jmax), area-based leaf nitrogen content (gN m-2), plant functional type classifications, location of the study sites, and monthly mean environmental gradients. To use our photosynthetic dataset, we request users to notify Ashehad A Ali and Chonggang Xu if the dataset is to be used in any publication. Unit for Vcmax is umol CO2 m-2 s-1 Unit for Jmax is umol electron m-2 s-1 Notes: Vcmax25 = Vcmax scaled at 25°C Jmax25 = Jmax scaled at 25°C TRF = temperature response function Vcmax25TRF1 = Vcmax25 using temperature response function 1 Vcmax25TRF2 = Vcmax25 using temperature response function 2 Vcmax25TRF3 = Vcmax25 using temperature response function 3 Vcmax25TRF4 = Vcmax25 using temperature response function 4 Jmax25TRF1 = Jmax25 using temperature response function 1 Jmax25TRF2 = Jmax25 using temperature response function 2 Jmax25TRF3 = Jmax25 using temperature response function 3 Jmax25TRF4 = Jmax25 using temperature response function 4
