A 143-year tree ring chronology from the Gemeindealpe site near Mariazell, Austria, covering the period from 118 to -25 calendar years before present. The dataset is archived by NOAA's World Data Service for Paleoclimatology and represents a study type of Tree Ring. It was last updated in the NOAA system in 1975.
Use Cases
- Reconstruct past summer temperatures by analyzing the ring_width parameter as a climate proxy.
- Calibrate climate models for the Alpine region using the precisely dated time_series from 118 to -25 BP.
- Investigate extreme climate events in Western Europe by identifying marker years of narrow or wide rings in the chronology.
- Perform cross-dating with other European tree ring series using the annual resolution of the ring_measurements.
Strengths
- Covers a 143-year period (118 to -25 BP), providing a multi-century climate proxy.
- Part of the authoritative International Tree-Ring Data Bank (ITRDB) collection curated by NOAA/NCEI.
- Geographic location (Austria, Western Europe) and study type (Tree Ring) are clearly documented.
Limitations
- The dataset is temporally stale, with a last update recorded in 1975, limiting modern methodological integration.
- Sample size and replication statistics (e.g., number of cores/trees) are unknown, affecting confidence in the chronology.
- The geographic coverage is limited to a single site (Gemeindealpe), which may not represent broader regional climate.
