Pine Mountain Combined, Georgia - ga022 Additional Site Information T.A. Knight N. Pederson Notes: The Pine Mountain chronology is composed of independent collections of QUMO on the Pine Mountain property by T.A. Knight and N. Pederson. They are combined here to improve replication. Some raw data here might have values of -8888 for years where the rings were distorted or otherwise not useful for dendroclimatology. The latest version of ARSTAN reads these as dummy variables and can in-fill these gaps. See the citation above for standardization methods. The ARSTAN standardization menu is below: opt plt tree-ring data type 1 !tucson ring-width format missing data in gap -9 0 !missing values estimated (no plots) data transformation 4 0 !spread/level power transform (no plots) first detrending 2 0 0 !1st-neg expon curve (k>0), no = opt 5 second detrending 6 0 0 !2nd-horizontal line through mean robust detrending 1 !non-robust detrending methods used interactive detrend 2 !interactive detrending used index calculation 2 !residuals or differences (rt-gt) ar modeling method 1 0 !non-robust autoregressive modeling pooled ar order 0 0 !minimum aic pooled ar model order fit series ar order 0 !pooled ar order fit to all series mean chronology 2 0 0 0 !robust (biweight) mean chronology stabilize variance 101 !spline stabilized (fixed 50% cutoff) common period years 1880 2000 !first and last years of common period site-tree-core mask SSSTTC !site-tree-core separation mask running rbar 40 20 0 !running rbar window/overlap (no plots) printout option 2 !summary & series statistics printed core series save 1 !series saved in tucson raw data format summary plot displays 3 !spaghetti and mean chronology plots stand dynamics stuf 0 0 !no stand dynamics analyses done running mean window 0 !running mean window width percent growth change 0 !percent growth change threshold std error threshold 0 !standard error limit threshold Reference: Pederson, N., A.R.
