Hoh Lake Tree Ring Chronology for Paleoclimate Reconstruction

Tree ring width data from a site in Washington state, United States, covering 422 years from 380 to -42 calendar years before present. The dataset is archived by the NOAA National Centers for Environmental Information under its World Data Service for Paleoclimatology. It was last updated in the NCEI system in 1992.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing the tree ring width time-series.
• Calibrate climate models using the 422-year chronology as a proxy record for the region.
• Study long-term growth patterns of Tsuga mertensiana (mountain hemlock) from the Hoh Lake site.
• Perform cross-dating with other regional tree ring chronologies using the annual resolution data.

Strengths

• Provides a 422-year continuous chronology for climate proxy analysis.
• Sourced from the authoritative NOAA/NCEI World Data Service for Paleoclimatology.

Limitations

• Temporal coverage ends 42 years before 1950 (the 'present' reference), limiting analysis of the most recent century.
• Data last updated in 1992, indicating potential staleness and lack of recent methodological revisions.
• Unknown sample depth (number of tree cores) underlying the chronology, affecting confidence in early periods.
