140-year tree ring chronology from the Blumone Malga site in Italy, covering the period from 110 to -30 calendar years before present. The dataset was archived by NOAA's World Data Service for Paleoclimatology and is associated with the Schweingruber study. It was last updated in the NOAA system in 1980.
Use Cases
- Reconstruct past temperature or precipitation anomalies using annual tree ring width measurements.
- Calibrate radiocarbon dating or other chronological models using the established tree ring chronology.
- Analyze climate response functions by correlating ring-width indices with instrumental climate data.
- Study extreme historical environmental events recorded as marker years or pointer years in the ring sequences.
Strengths
- Chronology spans 140 calendar years, providing a multi-decadal climate record.
- Data is curated and archived by the authoritative NOAA/NCEI World Data Service for Paleoclimatology.
Limitations
- Temporal coverage is relatively short (140 years) compared to many millennial-length tree ring chronologies.
- Data is from a single site (Blumone Malga, Italy), limiting spatial representativeness.
- The dataset's last recorded update was in 1980, potentially indicating stale metadata or versioning.
Provenance
- Source
- NOAA National Centers for Environmental Information (NCEI) World Data Service (WDS) for Paleoclimatology.
- Collection Method
- Tree ring analysis (dendrochronology), likely measuring ring widths from core samples.
- Time Range
- 110 to -30 calendar years before present (BP).
- Freshness
- null
- Geography
- Blumone Malga site, Italy, Southern Europe.
