This repository contains Global data used for “Global leaf-trait mapping based on optimality theory” published in GEB. Global_Maps_SLA represents climatology of published Global SLA used for comparison (details products see table 1 and figure 4). Global_Maps_Na represents climatology of published Global Narea used for comparison (details see table 1 and figure 4). Global_Maps_Nmass represents climatology of published Global Nmass used for comparison (details see table 1 and figure 4). TS_SLA is simulated time-series of SLA based on optimality theories from 1992 to 2015 TS_Na is simulated time-series of Narea based on optimality theories from 1992 to 2015 TS_Nmass is simulated time-series of Nmass based on optimality theories from 1992 to 2015 TS_LMA_decidudous is simulated time-series of deciduous LMA based on optimality theories from 1982 to 2016 TS_LMA_evergreen is simulated time-series of evergreen LMA based on optimality theories from 1982 to 2016 TS_Vcmax25 is simulated time-series of Vcmax25 based on optimality theories from 1982 to 2016
