Table 3 Spatial extent of extrapolation (i.e., the percentage of cells of the study area where extrapolation occurred) with single covariates and combinations of covariates. For dynamic covariates, the mean extent of extrapolation averaged over the 12 month period is provided, followed by the minimum and maximum monthly extents in parentheses. SST: sea surface temperature; PP: primary productivity; EKE: eddy kinetic energy.
