| Zusammenfassung |
| We constructed 1000-year long carbon and oxygen isotope chronologies of Silver fir (Abies
alba Mill.) from the temperate region of Franconia (northern Bavaria, Central Germany) with
the aim to carry out the climate reconstructions by using of multivariate models. The annual
variations of isotope signals in firs were strong influenced by airborne pollutants in the
second half of 20th century: the linear responses of 13C; 18O and 2H signals to SO2, O3 and
dust concentrations were high significant.
Therefore, we used the long meteorological data set, were the disturbed period could be
excluded for climate reconstructions. In this case, carbon isotopes correspond most
to spring/summer climate conditions as April to August mean temperatures and
June/July precipitation amount, oxygen show the strongest correlation to the July
relative air humidity and to the April to August mean temperatures. The correlations
between tree-ring signals and summer climate are high (p |
