142-year tree ring chronology from 94 to -48 calendar years before present, providing proxy climate data. The dataset is part of the NOAA/WDS Paleoclimatology archive, contributed by NOAA NCEI. It was last updated in the archive in 1998.
Use Cases
- Reconstruct past temperature or precipitation anomalies using the tree ring width chronology.
- Calibrate the chronology against other regional proxy records to validate climate signals.
- Analyze the growth response captured in the ring parameters to specific volcanic or climatic events within the 142-year period.
Strengths
- Covers a specific 142-year period (94 to -48 BP) for high-resolution temporal analysis.
- Archived and maintained by the authoritative NOAA National Centers for Environmental Information (NCEI).
Limitations
- Temporal coverage is limited to 142 years, which is short for some long-term climate trend analyses.
- Data is geographically specific to Manitoba, Canada, limiting broader spatial applications.
- The dataset was last updated in the archive in 1998, indicating potential staleness in metadata or documentation.
