NOAA/WDS Paleoclimatology archives a tree-ring dataset from the Tombstone Mountain area in Yukon Territory, Canada. The chronology covers a time period from 480 to -42 calendar years before present (BP), representing growth records from trees less than 100 years old. This study was published by NOAA National Centers for Environmental Information in 1992.
Use Cases
- Reconstruct past temperature or precipitation anomalies using the tree-ring width chronology.
- Calibrate climate models by comparing the proxy tree-ring record with instrumental data for the Yukon region.
- Analyze growth patterns in young trees (less than 100 years) to study recent environmental stressors.
- Establish a dated chronology for the Tombstone Mountain site to support regional climate synthesis.
Strengths
- Data spans 522 years of calendar years before present (480 to -42 BP).
- Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.
Limitations
- Temporal coverage ends at -42 BP, providing no data for the most recent decades.
- Geographic scope is limited to a single site (Tombstone Mountain, Yukon).
- Sample size and replication statistics are unknown from provided metadata.
