TRL scientists are dedicated to advancing the science of dendrochronology. The lab has an 'open-door' policy to visitors. The tree-ring and climate software made freely available here is one expression of our commitment to sharing knowledge with students, other scientists, and teachers.

The items offered here are free to download. Their only condition for use is that they be used responsibly. When necessary, we may be able to provide basic information or explain how to use and install software, but in general we can offer only limited user support.
