All data in the World Data Center for Paleoclimatology archive are contributed by research
scientists. Contributors and references are available in readme or data file headers. Here
is a Sample Data Citation.
 |
Dr. Fritz Schweingruber and colleagues at WSL-Birmensdorf (Swiss Federal Institute for Forest, Snow, and Landscape Research) have recently made the largest data contribution in the history of The International Tree-Ring Data Bank. The data set contains nearly 500 sites from around the world, including ring width and wood density measurements, and site chronologies. |
The WSL data was originally submitted to the WDC for Paleoclimatology in WSL-Birmensdorf format.
Access Measurement and Chronology Data in WSL-Birmensdorf Format
Recently, the data has been reformatted into the Tucson decadal format by the WDC for Paleoclimatology and is currently available in a raw format with missing values denoted by -999 or in a gap-filled format. The gap-filled files were produced using a recent version of Arstan. This program will be posted here in the near future, but for now it is available upon request from Dr. Edward Cook at Lamont-Doherty.
Chronology files were produced from the measurement files using Arstan. The chronology files as well as the Arstan output statistics can be downloaded by following the link below.
The WSL data and other NOAA Paleoclimatology Tree Ring data are available via an ArcIMS GIS interface that can be used to browse, query, and download the data from an interactive map.
