Hobbs Lake Tree Ring Chronology from Ontario, Canada

NOAA/WDS Paleoclimatology archives a tree ring chronology from the Hobbs Lake site in Ontario, Canada. The data covers a 447-year period from 403 to -44 calendar years before present (BP). This dataset was published by NOAA's National Centers for Environmental Information in 1994.

Use Cases

• Reconstruct historical temperature or precipitation anomalies from tree ring width measurements.
• Calibrate climate models by comparing the proxy chronology with instrumental records for the region.
• Analyze growth patterns and environmental stressors over the 447-year time span covered by the series.

Strengths

• 447-year temporal coverage provides a multi-century climate proxy record.
• Data is archived and curated by the authoritative NOAA World Data Service for Paleoclimatology.

Limitations

• Data is temporally stale, with a last recorded update in 1994.
• The geographic scope is limited to a single site (Hobbs Lake, Ontario).
• Specific sample depth, measurement parameters, and raw data formats are not provided in the description.
