Fig. 3: Principal components (PC) analysis of the water balance reconstructions for 11 to 0.25 ka.
From: Patterns and drivers of Holocene moisture variability in mid-latitude eastern North America
a Eigenvalues of the first ten principal components (PC). b–e Loadings for the reconstruction sites for PC1 (b) and PC2 (d). Sample scores of water balance reconstructions plotted across time for PC1 (c) and PC2 (e), where each sample comprises a set of reconstructed water-balance values from 53 sites for a single time point.
