DescriptionThe Dendro Database is a relational tree ring database containing tree ring data as well as their documentation and spatial information. All information is available over the Web. Almost all samples contained in the data collection were taken near the northern timberline or near the altitude timberline. In these extreme habitats, climatic conditions (mostly temperature) are known to have major influences on tree ring properties. Analysis of these tree ring data for reconstructing palaeoclimatic conditions have therefore been of interest to many scientists. About 14 000 cores of more than 40 tree species have been collected at about 600 locations all over the northern hemisphere. More than 1000 x-ray films have been exposed from the samples. Then, for each sample and each tree ring, several parameters were measured on the film: minimum density; maximum density; earlywood density; latewood density; earlywood width; latewood width; ring width; approximate age of pith. The dendrochronological data can be accessed by two web-based and linked applications: (1) Dendro Database Surfer, a database browser; and (2) Dendrochronology GIS, a GIS viewer (sample locations are plotted on a World Vegetation Cover Map).
