Temperature and precipitation limitation for FLUXNET2015 sites. Correlation between EOP and air temperature (Ta) or precipitation (Prec.) in the 2D plain of MAT and PSSM from SMAP. The color indicates the EOP correlation with pre-EOP Ta and precipitation. The symbols represent different ecosystem types, with symbol sizes indicating number of years being used from each site. The solid and dashed black lines, which separate the precipitation-limited and temperature-limited regions, are adopted from Fig. 2.
