Tree Ring Chronology from Lake Minotaur Low, Washington

127-year tree-ring chronology from an Abies lasiocarpa (ABLA) site in Washington, USA, provides paleoclimate data. The dataset, archived by NOAA NCEI's World Data Service for Paleoclimatology, covers the period from 85 to -42 calendar years before present. It was last updated in the repository in 1992.

Use Cases

• Calibrating climate models using the 127-year tree-ring width time-series as a proxy for past temperature or precipitation.
• Analyzing growth anomalies in the Abies lasiocarpa (ABLA) series to identify extreme climatic events like droughts.
• Cross-dating the WA113 ITRDB site chronology with other regional series to validate climate reconstructions.
• Studying the 'calendar years before present (BP)' timeline to understand environmental conditions during the late Holocene period.

Strengths

• 127-year temporal coverage from a specific tree species (Abies lasiocarpa) and site (WA113).
• Data is curated and archived by the authoritative NOAA NCEI World Data Service for Paleoclimatology.
• Includes precise geographic location (Washington, USA) and temporal bounds defined in calendar years BP.

Limitations

• Temporal coverage of 127 years is relatively short for some long-term paleoclimate trend analyses.
• Data is from a single tree species at a single site (Lake Minotaur Low), limiting spatial representativeness.
• The dataset metadata indicates a last update date of 1992, suggesting the record has not been recently revised.
