Fig. S1 Rainfall totals for all three years were similar, but intraseasonal signals, such as a mild drought that began around day of year (DOY) 200 in 2002, were readily apparent. LR, Look Rock, TN, USA.

Fig. S2 Comparative seasonal patterns of stem growth of red oak (Quercus rubra) were measured with manual dendrometers in (a) 2001–2003 at Look Rock, TN, USA and in (b) 2002 and 2003 at Twin Creeks. Data points represent averages of measurements for three trees at each date.
