Lower Current River, Missouri - MO042 Additional Site Information D.W. Stahle R. Guyette M.D. Therrell M.K. Cleaveland Purpose of Collection: paleoclimatic research Detrend method: Measurement type: Total ring width 1st Detrending method: Negative exponential; if cannot be fitted, then fit a regression line of any slope. 2nd Detrending method: If exp. is fitted, then a cubic spline with half power cutoff equal to series length is fitted; if the exp. cannot be fitted and a regression line is, then a spline with half power cutoff equal to 67% of the series length is fitted; In no case is a spline with half power cutoff less than 100 years fitted.
