Laboratory of Tree-Ring Research

Software

Some PC software for tree-ring applications is available from the Laboratory of Tree-Ring Research, although the Laboratory itself generally takes no responsibility for maintaining or supporting this software: see the disclaimers in documents associated with the various programs for more information.

• The ITRDB Program Library 2.0 is the latest version of the ITRDB Program Library, an extensive collection of programs to acquire, manipulate, analyse and display tree-ring data; they are accompanied by extensive documentation, including on-line help, and run from an easy to use DOS-based menu.
• The Dendrochronology Program Library is a subset of the programs included in version 2.0 of the ITRDB Program library, based on software which has been extensively used on mainframe machines.
• Fire History Application software manipulates event chronologies, in particular those related to fire scars and other fire history studies.
• The update to Precon 4.0 adds features and fixes bugs in software Hal Fritts has written to analyze the tree-ring response to monthly climatic variation.
• The demonstration of the TREERING 2.0 model of the response of cambial activity and ring structure to daily climatic variations by Alexander Shaskin (Institute of Forestry, Krasnoyarsk, Siberia) and Hal Fritts can also be found here.
