In today's class, we'll start out final exercise, which will introduce you to an industry-standard software tool used to extract environmental signals from tree-ring data.

To get ready for our exercise, first download a copy of the program 'ARTSTAN' from the software page at the Lamont-Doherty Tree-Ring Program.

, you should also download a copy of the Dendrochronological Program Library (DPL), which we may need for our work on Thursday.

For Mac users running OX X Lion or later, download the most recent version of ARSTAN and the DPL from the Lamont Lab's FTP site:

Third, download a copy of the ARSTAN manual (arstan_description.pdf).

Overview In this exercise, you'll use Google Earth to examine the global network of tree-ring data. We'll review the geographic distribution of tree-ring records and discuss why tree-ring data are common in some regions and rare in others (or completely absent). This assignment will help you understand why there are geographic biases in the application of tree-ring research and identify frontier regions for future research.

Useful resources Google Earth is available as a free download at http://www.google.com/earth/ index.html. The International Tree-Ring Data Bank is maintained by the NOAA Paleoclimatology Program and the World Data Center for Paleoclimatology at http://www.ncdc.noaa.gov/paleo/ treering.html.
