Scots pine (Pinus sylvestris L.) is a widely used tree species in European dendroclimatology studies due to its common distribution across much of the continent. Almost all studies find radial growth strongly related to summer temperature, a result reflecting site selection at high elevation/latitude environments where trees grow at their ecophysiological limits. Due to the amount of attention spent on these sites there is a geographical and seasonal bias in temperature reconstructions based upon tree-ring proxies in Europe. To overcome the limited availability of tree-ring data in temperate lowlands, we present a northern Poland ring-width chronology developed from living and historic Scots pine material with a strong common growth signal going back to AD 1200. Investigations into climate-growth relationships found year-to-year ring-width variability to be more strongly correlated to cold season temperature (November to April) prior to the growing season than summer temperatures during tree-ring formation. Based on this relationship it was possible to reconstruct cold season temperature conditions for the last 810 years. Spatial field correlations with gridded instrumental records indicated that the reconstruction provides relevant cold season temperature information across the land regions bordering the North Atlantic Ocean and Baltic Sea, lowlands and uplands of western and central Europe, and the eastern and central interior of Russia. Despite an unsuccessful attempt to find a stationary relationship with the North Atlantic Oscillation, comparisons with several cold season temperature reconstructions confirmed the long-term connection between our reconstructed temperature series for northern Poland and the wider area.
