NOAA NCEI archives this tree ring dataset from the Capra and Mt. Agarasului sites in Romania. It provides parameters for climate reconstruction covering a 97-year period from 66 to -31 calendar years before present. The data was contributed by Schweingruber and last updated in the NOAA system in 1981.
Use Cases
- Calibrating climate models using tree ring width as a proxy for past temperature or precipitation in Romania.
- Analyzing the time series of tree ring parameters to identify extreme climatic events within the 97-year coverage.
- Cross-dating this chronology (ITRDB ROMA004) with other regional series to build a longer, composite climate record.
- Studying growth anomalies in the Capra and Mt. Agarasului samples to infer environmental stressors for the period.
Strengths
- Data covers a specific 97-year period from 66 to -31 BP, providing a focused temporal snapshot.
- Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.
- Geographic location is precisely defined for Romania, Eastern Europe.
Limitations
- Temporal coverage is limited to 97 years, which is short for many climate trend analyses.
- The dataset was last updated in 1981, indicating potential staleness in metadata or curation methods.
- Sample size and replication depth (number of cores/trees) are unknown, affecting statistical confidence.
