A raw ring-width 'site master chronology' was compiled from the average of all cores.
Additionally, raw ring-width measurements were detrended for ontogenetic growth decline and compiled into a Master chronology using the program CRONOL (http://web.utk.edu/~grissino/).edu/~grissino/
Consequently, it can be difficult to isolate climatic from non-climatic variability in the raw ring width measurements, estimate the uncertainty associated with a reconstruction, and directly infer how specific techniques used to sequentially fit growth curves or to reconstruct climate influence the final estimates.
Dating accuracy was checked by calculating the correlation between the raw ring widths on a sample and the raw ring widths on the site master chronology, as well as shifting sample dates ±1 5 years.
Cores were dried and sanded, and raw ring widths were measured using the Velmex measuring stage and Measure J2X tree ring software.
For release events, a 10-year time window was used, based on the strategy of Nowacki and Abrams (1997), and the data were run using three sensitivity levels (minimum release factors): 10, 50 and 100%% growth change of raw ring widths.
It is important to note that this result applies to individual trees within a stand, not to stands growing at different stand densities at the same site, where mean wood density is related to mean ring width.
Fig. 2 Mean tree-ring width and tree-ring wood density according to aspect.
Specifically, the mean tree-ring width of the trees on the NE aspect was 4.2351 mm/y (±1.9423) and 3.0794 mm/y (±1.3147) on the SW aspect.
Particularly, the mean tree-ring width of trees on the NE aspect was approximately 40%% higher than on the SW, while the mean annual density was only 1%% higher than on the SW exposed slope (Fig. 2).
