The associated NCEI study type is Tree Ring. The data include parameters of tree-ring with a geographic location of Switzerland, Western Europe. The time period coverage is from 1195 to -54 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.

Recent samples were collected in the Swiss Alps at elevations between 1900 and 2200 m asl. Historic buildings are located in an altitudinal belt of 1500-1900 m asl, with their construction wood often originating from higher elevations: 110 samples derive from the Lötschental (1258-2004), 39 from the Simplon region (735-1510), and 31 from the Aletsch region and Simmental (1681-1986). Samples were processed using a WALESCH 2003 X-ray densitometer with a resolution of 0.01 mm, and brightness variations transferred into g cm-3 using a calibration wedge (Eschbach et al. 1995; Lenz et al.1976). The mean segment length (i.e., the average number of rings per core or disc sample) is 264 yr, with means of 239 and 289 yr for the recent and historic subsamples, respectively. Average MXD is 0.87 g cm-3, with little difference between the recent (0.90 g cm-3) and historic (0.84 g cm-3) material. The mean interseries correlation of the 180 MXD series is r~0.59, calculated using COFECHA (Holmes 1983). For regional tree-ring comparison, the GAR June–August temperature reconstruction for the A.D. 951-2002 period by Büntgen et al. (2005a) is used. This record combines 1527 subalpine larch and pine RW series from the Swiss and Austrian Alps. A fraction of this rather large wood collection is used for the density measurements as utilized in this current study, that is, 120 of the 180 larch MXD series derive from the RW dataset. ABSTRACT SUPPLIED BY ORIGINATOR: Annually resolved summer temperatures for the European Alps are described. The reconstruction covers the a.d. 755-2004 period and is based on 180 recent and historic larch [Larix decidua Mill.] density series. The regional curve standardization method was applied to preserve interannual to multicentennial variations in this high-elevation proxy dataset. Instrumental measurements from high- (low-) elevation grid boxes back to 1818 (1760) reveal strongest growth response to current-year June-September mean temperatures. The reconstruction correlates at 0.7 with high-elevation temperatures back to 1818, with a greater signal in the higher-frequency domain (r = 0.8). Low-elevation instrumental data back to 1760 agree with the reconstruction's interannual variation, although a decoupling between (warmer) instrumental and (cooler) proxy data before 1840 is noted. This offset is larger than during any period of overlap with more recent high-elevation instrumental data, even though the proxy time series always contains some unexplained variance. The reconstruction indicates positive temperatures in the tenth and thirteenth century that resemble twentieth-century conditions, and are separated by a prolonged cooling from 1350 to 1700. Six of the 10 warmest decades over the 755-2004 period are recorded in the twentieth century. Maximum temperature amplitude over the past 1250 yr is estimated to be 3.1C between the warmest (1940s) and coldest (1810s) decades. This estimate is, however, affected by the calibration with instrumental temperature data. Warm summers seem to coincide with periods of high solar activity, and cold summers vice versa. The record captures the full range of past European temperature variability, that is, the extreme years 1816 and 2003, warmth during medieval and recent times, and cold in between. Comparison with regional- and large-scale reconstructions reveals similar decadal to longer-term variability.
