AgeBandDecomposition: Age Band Decomposition Method for Tree Ring Standardization
Implements the Age Band Decomposition (ABD) method for
standardizing tree ring width data while preserving both low and high frequency
variability. Unlike traditional detrending approaches that can distort long term
growth trends, ABD decomposes ring width series into multiple age classes, detrends
each class separately, and then recombines them to create standardized chronologies.
This approach improves the detection of growth signals linked to past climatic and
environmental factors, making it particularly valuable for dendroecological and
dendroclimatological studies. The package provides functions to perform ABD-based
standardization, compare results with other common methods (e.g., BAI, C method, RCS),
and facilitate the interpretation of growth patterns under current and future climate
variability.
