树木年轮年表往往校准仪器气候记录使用相关性和响应函数。DENDROCLIM 2002使用自举置信区间来估计相关系数和响应函数系数的显著性。输入和输出文件选择以及分析选项都可以从用户友好的GUI中选择。最终结果以ASCII格式保存，并使用彩色编码符号绘制在屏幕上。DENDROCLIM 2002是现有的特定任务软件的扩展，该软件主要基于MS-DOS，并且是用户提供的用于统计软件包（如SAS）的代码。此外，DENDROCLIM 2002还包括通过进化和移动间隔来测试树木气候关系的时间变化的能力。这种简单的方法允许气候和树木生长之间的统计关系的一个完整的，动态的表示。一个例子，使用已公布的树木气候数据来说明该软件的分析和图形功能。(C)2004 Elsevier Ltd.保留所有权利。
Tree-ring chronologies are often calibrated against instrumental climate records using correlation and response functions. DENDROCLIM2002 uses bootstrapped confidence intervals to estimate the significance of both correlation and response function coefficients. Input and output file selection, as well as analytical options, are chosen from a user-friendly GUI. Final results are saved in ASCII format, and are plotted on screen using color-coded symbols. DENDROCLIM2002 is an extension of existing task-specific software, which is mostly MS-DOS based, and of available user-supplied code for statistical packages, such as SAS. In addition, DENDROCLIM2002 incorporates the ability to test for temporal changes of dendroclimatic relationships by means of evolutionary and moving intervals. This simple approach allows for a complete, dynamical representation of statistical relationships between climate and tree growth. An example using published dendroclimatic data is used to illustrate the analytical and graphical capabilities of the software. (C) 2004 Elsevier Ltd. All rights reserved.
