Abstract

Estimates of mean July-August temperatures for northern Fennoscandinavia are made back to 1700 using ring width and maximum latewood density chronologies of Pinus sylvestris L. (Scots pine) as predictors. Several prediction models are used and the best results are achieved with a simple two-variable model where climate in year t is estimated as a function of tree growth in years t and t + 1 at each site. The best reconstruction equation accounts for 56% of the temperature variance over a 74yr fitting period and 45% of the variance over a 39yr independent verification period. Relatively short-period variability (periods <10yr) is better reproduced in the reconstruction than is that at longer wavelengths. -from Authors
