eastern hemlock tree-ring chronology located near Mohonk Lake, New York
monthly climate data from the Mohonk Lake cooperative weather station located
about one kilometer from the tree-ring site at nearly the same elevation. The tree-
ring and climate records cover the periods 1850-1996 and 1896-2004, respectively.
So the joint period covered by the two datasets is 1896-1996. The correlation and
response functions shown here were calculated and tested as follows:

current growing season. This 16-month year is arranged to include two complete
