Alaskan Tree Ring Chronology for Water Supply Reconstruction

NOAA/WDS Paleoclimatology archives a tree-ring chronology from Alaska for water supply reconstruction. The dataset covers a 262-year period from 223 to -39 calendar years before present. NOAA National Centers for Environmental Information (NCEI) published this study in 1989.

Use Cases

• Reconstruct historical water supply levels using tree-ring width measurements.
• Analyze climate variability in Alaska over a 262-year period using the chronology data.
• Calibrate climate models with proxy data from the ITRDB AK029 site.
• Study long-term environmental changes by correlating tree-ring parameters with known climate events.

Strengths

• Covers a specific 262-year period (223 to -39 BP) for temporal analysis.
• Archived by the authoritative NOAA National Centers for Environmental Information (NCEI).

Limitations

• Data is temporally stale, last updated in 1989.
• Geographic coverage is limited to a single site in Alaska.
• Specific sample size, row count, and measurement parameters are unknown from the provided metadata.
