A 511-year tree ring chronology from Grassy Mountain in British Columbia, Canada, covering the period from 462 to -49 calendar years before present. The dataset was archived by NOAA's World Data Service for Paleoclimatology and is associated with the NCEI study type 'Tree Ring'. The data was last updated in the NOAA system in 1999.
Use Cases
- Reconstruct past temperature or precipitation anomalies by analyzing the width and density of annual tree rings.
- Calibrate climate models for the Holocene period using the 511-year proxy record from this specific site.
- Study ecological responses to climate events by examining growth patterns within the chronology.
- Perform cross-dating with other regional tree ring chronologies to validate and extend climate reconstructions.
Strengths
- Covers a 511-year time period (462 to -49 BP)
- Geographically specific to a site in British Columbia, Canada
Limitations
- Data is temporally stale, last updated in 1999.
- Sample size and replication depth within the chronology are unknown.
- Geographic scope is limited to a single mountain site.
