Records of past temperature, precipitation, and other climate variables derived from paleoclimate proxies. Parameter keywords describe what was measured in this data set. Additional summary information can be found in the abstracts of papers listed in the data set citations. STUDY NOTES: The data consists of two timeseries representative of Northern Hemisphere growing season temperatures for the period 1400-1994, derived from means of 383 maximum latewood density chronologies from the northern Boreal forest. Both series are given in dimensionless standardised anomalies, and one has also been rescaled to give an estimate of Northern Hemisphere land and marine temperature anomalies.
