Summarized information for the tree-ring chronologies used for the summer EU JSL reconstruction
The unfiltered adjusted chronologies were used in the final summer EU JSL reconstruction. MXD represents tree-ring maximum density, RW represents tree-ring width, and BI represents tree-ring blue intensity. #Indicates that a high-pass filter (the difference between the current year and the previous year) was applied. r represents Pearson’s correlation coefficient. **Represents significance level p ≤ 0.01 and *represents significance level p ≤ 0.05 in the table.
