White Pass Tree Ring Chronology For Climate Reconstruction

462 calendar years of tree-ring width data from 430 to -32 years before present, providing a proxy climate record. The dataset is part of the NOAA/WDS Paleoclimatology collection, specifically from the White Pass A site in Washington, USA. It was archived by NOAA National Centers for Environmental Information and last updated in 1982.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing the tree-ring width time-series as a climate proxy.
• Calibrate climate models using the 462-year chronology from the White Pass A site for the Pacific Northwest region.
• Study the growth patterns of Tsuga mertensiana (TSME) trees in response to historical environmental stressors recorded in the ring data.
• Perform cross-dating with other regional tree-ring chronologies using the annual resolution of the ring-width series.

Strengths

• Covers a continuous 462-year period (430 to -32 BP), providing a multi-century climate record.
• Sourced from the authoritative NOAA National Centers for Environmental Information (NCEI) World Data Service for Paleoclimatology.
• Data is specific to a single tree species (Tsuga mertensiana) and geographic location (White Pass, Washington), ensuring consistency.

Limitations

• Data collection ended in 1982, making the record potentially stale for modern calibration studies.
• The geographic coverage is limited to a single site in Washington, USA, which may not be representative of broader regional climates.
• Without column details, the specific measured parameters (e.g., standardized indices, raw measurements) are unknown.
