Mount Adams Tree Ring Chronology from 260 BC to 42 BC

Tree ring width measurements from Tsuga mertensiana (TSME) trees at Mount Adams, Washington, provide a 302-year climate proxy record. The data, archived by NOAA's National Centers for Environmental Information, covers the period from 260 to 42 calendar years before present. This paleoclimate study was published in 1992.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing the time-series of tree ring width measurements.
• Calibrate regional climate models using the 302-year proxy record from Tsuga mertensiana (TSME) samples.
• Study the frequency of climatic events like droughts by identifying patterns of narrow rings within the chronology.
• Compare this high-elevation Mount Adams site chronology with other regional tree ring datasets to assess spatial climate patterns.

Strengths

• 302-year continuous chronology from 260 to 42 calendar years BP.
• Data originates from the authoritative NOAA NCEI World Data Service for Paleoclimatology.
• Specific geographic location (Mount Adams, Washington, USA) and species (Tsuga mertensiana) are documented.

Limitations

• Temporal coverage is limited to a specific 302-year period in the pre-Common Era.
• Data is geographically focused on a single high-elevation site in Washington state.
• The dataset was last updated in 1992, indicating it is a static, legacy archive.
