Reconstructed Summer Degree Days in Central Alaska and Northwestern Canada since 1524
Three time series based on precisely dated annual tree-ring widths have been used to reconstruct June plus July degree days for the central Alaska and northwestern Canada region. The time series are the longest recently developed chronologies for the area and represent 57 core samples from 27 trees....
