Adams Lake Tree Ring Chronology For Paleoclimate Analysis

NOAA/WDS Paleoclimatology archives a tree-ring chronology from Adams Lake, British Columbia, Canada. The data covers a period from 177 to -46 calendar years before present (BP), representing over two centuries of environmental proxy data. This study was published by the NOAA National Centers for Environmental Information in 1996.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree-ring width chronology as a proxy.
• Calibrate climate models by comparing the tree-ring time-series data with instrumental records for the region.
• Analyze growth patterns in Abies lasiocarpa (ABLA) to study ecological responses to historical environmental stressors.
• Establish a dated chronology for the site to support cross-dating with other regional tree-ring studies.

Strengths

• Time series spans over 200 years (177 to -46 BP), providing a multi-century climate proxy.
• Data is curated and archived by the authoritative NOAA National Centers for Environmental Information (NCEI).

Limitations

• Dataset is temporally stale, with a last update recorded in 1996, potentially lacking modern revisions.
• Specific sample size, replication statistics, and measurement parameters are not provided in the available metadata.
