    <gco:CharacterString>This archived Paleoclimatology Study is available from the NOAA National Centers for Environmental Information (NCEI), under the World Data Service (WDS) for Paleoclimatology. The associated NCEI study type is Climate Reconstruction. The data include parameters of climate reconstructions|tree ring with a geographic location of Northern Hemisphere. The time period coverage is from 1350 to -52 in calendar years before present (BP). See metadata information for parameter and study location details. Please cite this study when using the data.</gco:CharacterString>

    <gco:CharacterString>STUDY NOTES: Annually resolved summer temperature reconstruction for the northern hemisphere midlatitudes. The 15 proxy records are maximum-latewood-density chronologies with a minimum length of 600 years and a significant local summer temperature signal. The proxy composite is scaled against June-August temperatures from the CRUTEM4v network (30-90N). 
ABSTRACT SUPPLIED BY ORIGINATOR: Annually resolved and millennium-long reconstructions of large-scale temperature variability are primarily composed of tree ring width (TRW) chronologies. Changes in ring width, however, have recently been shown to bias the ratio between low- and high-frequency signals. To overcome limitations in capturing the full spectrum of past temperature variability, we present a network of 15 maximum latewood density (MXD) chronologies distributed across the Northern Hemisphere extratropics. Independent subsets of continental-scale records consistently reveal high MXD before 1580 and after 1910, with below average values between these periods. Reconstructed extratropical summer temperatures reflect not only these long-term trends but also distinct cooling pulses after large volcanic eruptions. In contrast to TRW-dominated reconstructions, this MXD-based record indicates a delayed onset of the Little Ice Age by almost two centuries. The reduced memory inherent in MXD is likely responsible for the rapid recovery from volcanic-induced cooling in the fourteenth century and the continuation of warmer temperatures until ~1600.</gco:CharacterString>
