The associated NCEI study type is Tree Ring. The data include parameters of tree-ring with a geographic location of Sweden, Scandanavia. The time period coverage is from 843 to -57 in calendar years before present (BP). See metadata information for parameter and study location details. Please cite this study when using the data. Tree ring data from the International Tree Ring Data Bank and World Data Center for Paleoclimatology archives. Most data sets include raw treering measurements (most are annual ring width, with some collections of earlywood or latewood width or wood density), plus chronologies (standardized growth indices for a site compiled from multiple treering samples). Reconstructions of climate variables are included with some of these data sets. Each data type is stored in a separate data file; the data type is coded into the file name.

Henceforth, these data are referred to as ITRAX data, and they consist of more than 50 radial measurement series collected from both living and dead trees. Two 10 mm cores, from ~1.3 m above the ground, were collected from each living or standing dead tree. From dead trees, lying on the ground or submerged in water, thick discs were cut from the trunks with a chainsaw at about 1–1.5 m above the root collar. The two MXD chronologies, SH (1107–1827, with a gap between 1292 and 1315) and ITRAX (1292–2006), were combined into a single chronology (1107–2006). This combined chronology consists solely of the SH data before 1292, ITRAX alone for 1292–1315, the average of the two during the period 1316–1827, and ITRAX data alone after 1827. The variance in each chronology was stabilized according to the Briffa RBAR-weighted method implemented in ARSTAN software (Cook and Krusic 2005), in order to compensate for variations in sample depth in the chronologies. ABSTRACT SUPPLIED BY ORIGINATOR: Dendroclimatological sampling of Scots pine (Pinus sylvestris L.) has been made in the province of Jämtland, in the west-central Scandinavian mountains, since the 1970s. The tree-ring width (TRW) chronology spans several thousand years and has been used to reconstruct June-August temperatures back to 1632 bc. A maximum latewood density (MXD) dataset, covering the period ad 1107-1827 (with gap 1292-1315) was presented in the 1980s by Fritz Schweingruber. Here we combine these historical MXD data with recently collected MXD data covering ad 1292-2006 into a single reconstruction of April-September temperatures for the period ad 1107-2006. Regional curve standardization (RCS) provides more low-frequency variability than “non-RCS” and stronger correlation with local seasonal temperatures (51% variance explained). The MXD chronology shows a stronger relationship with temperatures than the TRW data, but the two chronologies show similar multi-decadal variations back to ad 1500. According to the MXD chronology, the period since ad 1930 and around ad 1150-1200 were the warmest during the last 900 years. Due to large uncertainties in the early part of the combined MXD chronology, it is not possible to conclude which period was the warmest. More sampling of trees growing near the tree-line is needed to further improve the MXD chronology.
