Thornton Lakes Tree Ring Chronology from Washington State

NOAA/WDS Paleoclimatology archives a tree ring chronology from the Thornton Lakes site in Washington, USA. The data covers a time period from 244 to -42 calendar years before present. This study was published by NOAA National Centers for Environmental Information in 1992.

Use Cases

• Reconstruct past climate variables like temperature or precipitation using the tree ring width chronology.
• Calibrate the tree ring chronology against known climate events within the 286-year time span.
• Analyze growth patterns in Tsuga mertensiana (TSME) trees from a specific geographic location in Washington.

Strengths

• Data spans a continuous 286-year period (244 to -42 BP).
• Sourced from the authoritative NOAA National Centers for Environmental Information.

Limitations

• Data is temporally stale, last updated in 1992.
• Geographic coverage is limited to a single site in Washington State.
• Sample size and replication depth are unknown from the metadata.
