Figure 7: Tree-Ring Width Model-Data Comparison: the effect of detrending method on β. For each site, the original measured TRW is plotted in black, along with the PSM (VS-Lite) inputs of temperature (red), precipitation (blue), and the simple VS-Lite generated pseudoproxy data (dark green dashed), which does not include detrending or growth-curve. The negative-exponential detrending method was applied to both the real proxy data and the VS-Lite generated pseudoproxy data (bright green). To estimate reasonable errors for simulated TRW, we took reported errors for the estimated growth parameters in 100 randomized possibilities (grey).
