Fig. 3: Temporal evolution of correlations of GPP-ET derived from Trendy models.
From: Recent weakening of carbon-water coupling in northern ecosystems
a Times series of GPP-ET correlation calculated using 5-years moving windows. Black line indicates the ensemble mean of the 13 models, and the gray dashed lines indicate the time series of GPP-ET of each Trendy model. b Trend of GPP-ET correlation during the study period. ** and * denote the significant levels at p < 0.01 and p < 0.05, respectively.
