Frequency Domain Tree-Ring Standardization
Abstract:Prior to modeling tree-ring variation from climatic variables, an effort is made to standardize the tree-ring series by removing nonclimatic variance. A number of methods for standardizing tree-ting series in the frequency domain are presented along with a method for reducing end-fit problems. A technique for controlling the stiffness of a smoothing spline using frequency domain considerations is derived using matrix theory, and the spline is shown to be similar to other frequency domain methods. The results presented here elucidate earlier developments and allow for a more general application of frequency domain smoothing procedures. FOR. SCI. 39(1):55-65.
