E
Eur 001.d18O +	The uppermost point marks the present-day conditions in Spannagel at +1.8C and y18O= 7.8x. The average temperature in the Alps during the coldest period between 1688 and 1698 coincided with the Maunder Minimum. As derived from Luterbacher's data the average temperature in this period was 1.0 (F0.5) 8C about 1.8 8C lower than in the period between 1995 and 1998.  +
Eur 002.temperature +	We used multiple linear regression (MLR) to establish a calibration model that explains 84% of the variance of summer (JJAS) temperature during the calibration period 1864_1950. We then applied the calibration model downcore to develop a quantitative summer temperature reconstruction extending back to AD 1177.  +
Eur 003.temperature +	The average inferred July temperatures between ca 1900 and 2001 AD were significantly warmer (p < 0.05) than the climate reference period (1961-1990) by 1C which is in agreement with the instrumental data. The inferred July temperatures were in the same range as the inferred temperatures during the last part of the MCA suggesting that during the 20th century at Lake Silvaplana the chironomid-inferred temperatures do not exceed the natural climate variability of the past millennium.  +
Eur 005.temperature +	Calibrating and verifying the MXD chronologies against the instrumental temperature data showed a promising opportunity to reconstruct warm-season (May through September) temperature variability  +
Eur 006.temperature +	By refining dendroclimatological methods the time-series were composited to a mean series and calibrated (1756_1841; r2 = 66%) against Stockholm January_April temperatures.  +
Eur 007.temperature +	When compared to local and regional instrumental records since ca 1760 AD significant (p < 0.01) relationships (rPearson > 0.5) are obtained suggesting that chironomids accurately register the changes in temperature for the past ca 250 years  +
Eur 008.d18O +	The positive correlation between 013C series of the stalagmites and the surface temperature series shown in the previous section is robust in the three samples but requires some further discussion.  +
Eur 009.d18O +	Here we reconstruct thermocline temperature and salinity in this region from AD 818 to 1780 using paired _18O and Mg/Ca ratio measurements of foraminifer shells from a subdecadally resolved marine sediment core.  +
Eur 010.temperature +	SST determinations based on the alkenone index UK37 indicate annual upwelling in tensity as the determinant factor for SST variability confirming the Tagus results (Abrantes et al. 2009)  +
Eur 014.MXD +	The final reconstruction (N-scan) was calibrated against regional JJA temperature (r 1876_2006 = 0.77) and spans the 138 bc_ ad 2006 period.  +
Eur 016.trsgi +	Using AD 1901_1950 as the calibration period the Pearson's correlation coefficient between grid data and reconstruction is 0.34 and for verification is 0.47  +
Eur 017.trsgi +	This composite record includes living trees historical timber and subfossil wood and correlates at 0.72 to 0.92 with interannual to multidecadal variations in instrumental June-to-August (JJA) temperature (1864_2003)  +
Eur 018.MXD +	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).  +
Eur 019.trsgi +	While the highest correlation of 0.53 is gained from the HISTALP southwest subset significantly lower correlation of 0.27 originates from the low-resolution HadCRUT3v data (Brohan et al. 2006) both against June_August temperature means.  +
Eur 020.trsgi +	Regional chronologies based on nested PCs display high correlation coefficients in the two calibration periods: both regression-calibrated (r1900_1952 = 0.81 and r1953_2005 = 0.75 on average) and scaling-calibrated (r1900_1952 = 0.73 and r1953_2005 = 0.80 on average). Similarly REs are also high (well above 0) for the two verifications.  +
Eur 022.temperature +	For overlapping period (1760-1854) the documentary data series correlate with instrumental temperatures most strongly in winter (86% explained variance in January) and least in autumn (56% in September). For annual average temperatures 81% of the variance is explained. Elevation estimated from GoogleEarth; rounded to 100 m  +
