Cass Lake Tree Ring Chronology for Paleoclimate Analysis

Tree ring width measurements from Cass Lake, Minnesota, provide a 203-year climate proxy record from 165 to -38 calendar years before present. The dataset is archived by NOAA's World Data Service for Paleoclimatology. Data was published by the NOAA National Centers for Environmental Information.

Use Cases

• Reconstruct annual temperature or precipitation anomalies using the tree ring width time-series.
• Calibrate climate models by comparing the ring width chronology with instrumental records.
• Analyze growth response to environmental stressors by examining year-to-year variability in the ring data.
• Establish a regional dendrochronological master chronology using this site-specific record.

Strengths

• Time-series covers a 203-year period (165 to -38 BP).
• Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.

Limitations

• Temporal coverage ends 38 years before 1950, limiting overlap with modern instrumental records.
• Sample size and replication statistics for the tree ring chronology are unknown.
• Geographic coverage is limited to a single site (Cass Lake, Minnesota).
