Bruno Lake Tree Ring Chronology for Canadian Paleoclimate

NOAA/WDS Paleoclimatology archives a tree ring dataset from Bruno Lake, Manitoba, Canada. The data provides a chronology covering the period from 128 to -38 calendar years before present. This study was contributed by Schweingruber and is managed by NOAA's National Centers for Environmental Information.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree ring width chronology.
• Calibrate climate models by comparing the tree ring proxy data with instrumental records for the region.
• Analyze growth patterns to infer ecological disturbances or stress events during the covered time period.
• Cross-date this chronology (ITRDB CANA038) with other regional tree ring series to validate climate signals.

Strengths

• Chronology spans 166 calendar years, providing a multi-century climate proxy.
• Data is part of the authoritative International Tree-Ring Data Bank (ITRDB) and NOAA/WDS network.

Limitations

• Dataset is temporally stale, with a last update date of 1988.
• Specific sample size, measurement parameters, and replication statistics are not provided in the input.
