In micro-densitometry of wood it is standard procedure to extract resin and other soluble compounds before X-ray analysis to eliminate the influence of these extractives on wood-density. Dendrochemical studies using X-ray fluorescence analysis on the

Reanalysis data show an increasing trend in Arctic precipitation over the 20th century, but changes are not homogenous across seasons or space. The observed hydroclimate changes are expected to continue and possibly accelerate in the coming centur

Despite the emergence of new high-resolution temperature reconstructions around the world, only a few cover the Medieval Climate Anomaly (MCA). Here we present C-Scan, a new Scots pine tree-ring density-based reconstruction of warm-season (April–Se

Here we explore two new tree-ring parameters, derived from measurements of wood density and blue intensity (BI). The new proxies show an increase in the interannual summer temperature signal compared to established proxies, and present the potential

Fennoscandia has a strong tradition in dendrochronology, and its large tracts of boreal forest make the region well suited for the development of tree-ring chronologies that extend back several thousands of years. Two of the world's longest continuou

An improved and extended Pinus sylvestris L. (Scots Pine) tree-ring maximum density (MXD) chronology from the central Scandinavian Mountains was used to reconstruct warm-season (April–September) temperature back to 850 CE. Due to systematic bias fr

Dendroclimatology, i.e. using tree-ring data to reconstruct past climates, in Fennoscandia has a strong tradition. Due to the high-latitude location of the region, trees are sensitive to climate; in general to temperatures during summer. However, a s
