Project: Dendroclimatic History of the United States, Contract: E-41-70(N) / 1970 Final Report Prepared for: Laboratory for Environmental Data Research, Environmental Data Service, Weather Bureau, Environmental Science Services Administration, United States Department of Commerce / November 9, 1970 / Ring widths from trees on certain sites reflect climatic variation. Therefore, long time series derived from replicated and precisely dated
ring-width chronologies may be utilized to extend climatic records into prehistoric times. Multivariate analyses of tree -ring chronologies from
western North America are used to derive response functions from which one can ascertain what climatic information each ring -width chronology
contains. In addition, multivariate analyses are utilized to calibrate a large number of ring -width chronologies of diverse response functions
and from widely dispersed sites with a large number of regional climatic variables. A series of transfer functions are derived which allow estimates of anomalous climatic variation from tree -ring records.
Reconstructions of anomalous variation in atmospheric circulation for portions of the northern hemisphere back to A.D. 1700 are obtained by applying the transfer functions to tree -ring data for time periods when
ring data are available but climatic data are not.
