Nooksak Falls Tree Ring Chronology for Paleoclimate Study

Tree ring width data from a Douglas fir (Pseudotsuga menziesii) site at Nooksak Falls, Washington, provides a 428-year paleoclimate record. The chronology, archived by NOAA's World Data Service for Paleoclimatology, covers the period from 402 to -26 calendar years before present. This dataset was published by the NOAA National Centers for Environmental Information.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing the annual tree ring width series.
• Calibrate climate models using the 428-year proxy record of environmental conditions from the Nooksak Falls site.
• Study growth patterns of Pseudotsuga menziesii (Douglas fir) in response to historical climate events within the specified time range.
• Perform cross-dating analysis by comparing this ITRDB WA019 chronology with other regional tree ring datasets.

Strengths

• 428-year temporal coverage from 402 to -26 calendar years BP
• Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology

Limitations

• Sample size and replication depth for individual years are unknown from the description
• Data has not been updated since its original publication in 1976, making it temporally stale for recent climate studies
