Nome Creek Treeline Tree Ring Chronology From Alaska

Tree ring data from the Nome Creek treeline site in Alaska, covering a period from 175 to -47 calendar years before present. The dataset is archived by the NOAA National Centers for Environmental Information under its Paleoclimatology program. It was last updated in the repository in 1997.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree ring width chronology.
• Calibrate the chronology against known climate events within the 222-year time span.
• Analyze growth response and treeline position shifts in Alaska over the recorded period.

Strengths

• Time series covers a 222-year period (175 to -47 BP).
• Data is curated and archived by the authoritative NOAA/NCEI World Data Service for Paleoclimatology.

Limitations

• The dataset's last known update was in 1997, indicating potential staleness in metadata or access methods.
• Specific sample size, measurement parameters, and replication details are not provided in the input.
