eaglecol: Tree-ring indicies for Douglas Fir, Colorado, 1107-1964.

Description

Tree-ring indicies for Douglas Fir, Colorado, 1107-1964. There are 858 consecutive values. When the environment is suboptimal, tree ring growth is limited by the climate, usually either ambient temperature or precipitation. For this tree-ring time series, the tree is located on a mountain and the limiting growth factor is temperature.
