Annually resolved δ<sup>2</sup>H tree-ring chronology of the lignin methoxyl groups from Germany reflects averaged Wester…

2019

Abstract. Stable hydrogen isotopes ratios of lignin methoxyl groups (expressed as δ2HLM) of wood have been shown to reflect the climate-sensitive δ2H values of precipitation (expressed as δ2Hprecip) modulated by a large uniform negative isotope fractionation. However, a detailed calibration study among temporal variabilities of δ2HLM in tree-ring series, site-specific δ2Hprecip and climate parameters has not been performed yet. Here, we present annually resolved δ2HLM values from nine tree-ring series (derived from four Fagus sylvatica L. trees) collected near stations of the Global Isotope Network of Isotopes in Precipitation (GNIP) and the Deutsche Wetterdienst (DWD) meteorological observ…

Tree-ring δ2H values from lignin methoxyl groups indicate sensitivity to European-scale temperature changes

2020

Abstract Stable hydrogen isotope ratios of lignin methoxyl groups (δ2HLM) of wood have been shown to reflect climate-sensitive δ2H values of precipitation (δ2Hprecip). However, a detailed calibration study between high-resolution δ2HLM and δ2Hprecip data has not been performed yet. Here, we present annually resolved δ2HLM values from nine tree-ring series (derived from four Fagus sylvatica L. trees) collected near a station of the Global Isotope Network of Isotopes in Precipitation (GNIP) and the meteorological observatory at Hohenpeisenberg (Germany; ~48°N, 11°E). The nine δ2HLM tree-ring series show highly significant inter-series correlations (Rbar = 0.52) over the common period of overl…

Wind gustiness and sulphur dioxide concentration in the urban area of Barcelona, Spain

1991

Abstract Data on aerosols and wind parameters recorded at the Barcelona Meteorological Observatory were analysed to determine their relation to wind gustiness, defined according to the criteria used at Brookhaven National Laboratory. The relation between wind gustiness and wind speed and direction was analysed, together with the annual and monthly variation. The relation between the concentration of sulphur dioxide and wind gustiness was also investigated, and proved to be a very useful indicator in this kind of analysis, especially in local studies.
