Laboratory of Tree-Ring Research, University of Arizona

Welcome to the Laboratory of Tree-Ring Research at the University of Arizona.

History and activities

The Laboratory of Tree-Ring Research was organized in 1937 as an outgrowth of the pioneering tree-ring studies initiated by Andrew Ellicott Douglass at the University of Arizona in 1906. A division of the College of Arts and Sciences, the Laboratory conducts a unique program of teaching and research in all aspects of dendrochronology. Graduate-level instruction is offered through cooperating academic departments, and a limited number of graduate research assistantships are available to qualified students. Current research efforts are directed toward the quantification of tree-ring parameters, the establishment of new tree-ring chronologies throughout the world, the use of tree-rings in the study of forest ecosystems, the reconstruction of paleohydrologic and paleoclimatic variables, and the documentation and development of prehistoric chronological controls. Along with the world's largest collection of tree-ring specimens from living trees and ancient timbers, the Laboratory maintains a variety of specialized equipment and data files containing processed tree-ring chronologies, relevant climatic and hydrologic records, and archaeological tree-ring dates and site information. Sponsored research is currently funded by several agencies, including the National Science Foundation, the U.S. Department of Energy, the Environmental Protection Agency, the USDA Forest Service and the USDI National Parks Service.

Other Laboratory information

There is a Laboratory personnel list, a partial list of research interests and list of courses. We also have a rather short list of personal home pages. The Laboratory maintains a limited archive of software and data. Unfortunately our FTP server will not work with some client programs, including the current version of Mosaic for Windows.

Useful Information Elsewhere

The RING Foundation in The Netherlands is interested in dendrochronology in Europe, and in particular the applications for archaeological dating. The most useful single collection of tree ring data is the International Tree Ring Data Bank. This is just one of the archives forming the National Geophysical Data Center. There is an e-mail distribution list for dendrochronology: to subscribe send a message to LISTSERV@listserv.Arizona.EDU containing nothing but the text SUBSCRIBE ITRDBFOR followed by your first and last names, e.g.

SUBSCRIBE ITRDBFOR Andrew Douglass

(the subject of the message does not matter). People working on dendroclimatology need access to meteorological data, and good places to start looking are the Sources of Meteorological Data FAQ the National Climatic Data Center and the NCAR Data Archive.
