Two versions of the chronology are developed. The cubic smoothing spline (SPL) chronology, standardized # with a fixed 80 year spline function, retains decadal and higher frequency variation. The regional curve standardization # (RCS) chronology uses regional curve standardization to retain additional lower frequency variation from the same # data. Calibration (1879-1978) of these chronologies with March-August precipitation indicates they explain 40% (SPL) # and 34% (RCS) of the variability in the instrumental precipitation record. The SPL reconstruction models the high frequency # variation better, whereas the RCS reconstruction tracks the low-frequency trends more robustly. It suggests # that spring-summer precipitation was above the long-term average for the periods 1730-1810 and 1870-2000, about # average between 1560 and 1610 and that significantly drier periods occurred during 1510-60, 1610-35, 1660-1730 and # 1830-70. The low-frequency trends of the RCS reconstruction during the 19th century were verified by comparison with a # regional precipitation series derived from 14 long precipitation records from central Europe. Better verification results were # obtained using the original (non-homogenized) records over this interval. These results suggest that some low-frequency # variability may have been removed during correction of these early records. Periods of synchronous decadal variability # were observed between the SPL series and independent dendroclimatic reconstructions from central Europe. The RCS # reconstruction is the first dendroclimatic precipitation reconstruction in Europe to capture low-frequency information. # These long-term trends, however, are difficult to verify owing to the paucity of other proxy precipitation records in # central Europe that portray low-frequency information. Further verification and testing of the RCS reconstruction will # require the development of additional reconstructions from tree-rings (or other proxy data series) that similarly target # low-frequency variability. #------------------- # Site Information # Site_Name: Blaue-Stern-Gasse 3 Regensburg Historical Timbers # Location: Bavaria # Northernmost_Latitude: 49.0167 # Southernmost_Latitude: 49.0167 # Easternmost_Longitude: 12.1 # Westernmost_Longitude: 12.1 # Elevation: #------------------- # Data Collection # Collection_Name: GERM107 # Earliest_Year: 1627 # Most_Recent_Year: 1678 # Time_Unit: AD # Notes: #------------------- # Species # Species_Name: Picea abies (L.)
