Large-scale millennial length Northern Hemisphere (NH) temperature reconstructions have
been progressively improved over the last 20 years as new datasets have been developed …

Climate field reconstructions from networks of tree-ring proxy data can be used to
characterize regional-scale climate changes, reveal spatial anomaly patterns associated …

Global and hemispheric temperature reconstructions provide an important means of placing
recent anthropogenic temperature trends in the context of preindustrial climate variations …

Across western North America (WNA), 20th-21st century anthropogenic warming has
increased the prevalence and severity of concurrent drought and heat events, also termed …

X‐ray microdensitometry on annually resolved tree‐ring samples has gained an exceptional
position in last‐millennium paleoclimatology through the maximum latewood density (MXD) …

Blue intensity (BI) has the potential to provide information on past summer temperatures of a
similar quality to maximum latewood density (MXD), but at a substantially reduced cost. This …

Water availability is fundamental to societies and ecosystems, but our understanding of
variations in hydroclimate (including extreme events, flooding, and decadal periods of …

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 …

Combining nine tree growth proxies from four sites, from the west coast of Norway to the
Kola Peninsula of NW Russia, provides a well replicated (> 100 annual measurements per …

Wood microdensitometry is the analysis of radial variations of density at the annual or intra-
annual growth ring level. Density is related to wood quality, biomass, carbon content, tree …
