Alaskan Tree Ring Chronology from 370 to -48 BP

NOAA/WDS Paleoclimatology archives the Jacoby - Hawkins Hill tree ring chronology from Alaska. The dataset provides tree ring parameters for reconstructing past climate, covering a period from 370 to -48 calendar years before present. NOAA National Centers for Environmental Information (NCEI) maintains this archived study, last updated in 1998.

Use Cases

• Reconstruct historical temperature or precipitation anomalies using the tree ring width chronology.
• Calibrate climate proxy models by analyzing the relationship between ring parameters and known climate events within the 418-year span.
• Study ecological responses to past climate shifts in Alaska by examining growth patterns in the tree ring series.
• Compare this high-latitude tree ring chronology with other proxy records to analyze hemispheric climate teleconnections.

Strengths

• 418-year temporal coverage from 370 to -48 BP provides a multi-century climate record.
• Data is archived and curated by the authoritative NOAA National Centers for Environmental Information (NCEI).

Limitations

• Data is temporally stale, with a last update date of 1998, potentially lacking modern reanalysis.
• The specific tree ring parameters and measurement methods are not detailed without consulting full metadata.
