Coddington Lake Tree Ring Chronology for Paleoclimate Reconstruction

198 calendar years of tree ring data, from 160 to -38 years before present, providing a proxy record for past climate conditions. The dataset is part of the NOAA/WDS Paleoclimatology archive, specifically from the PIRE-ITRDB collection for site MN024. It was published by NOAA NCEI, with the last known update in 1988.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing the tree ring width time-series.
• Calibrate climate models using the high-resolution, annually-resolved proxy data from this chronology.
• Study regional climate extremes and their frequency by examining the variance in the ring width parameter over the 198-year period.
• Perform cross-dating with other tree ring chronologies using the shared time-series data to validate climate signals.

Strengths

• Covers a continuous 198-year period suitable for climate trend analysis.
• Data is curated and archived by the authoritative NOAA National Centers for Environmental Information (NCEI).

Limitations

• Temporal coverage ends at -38 BP, making the most recent data over 2000 years old and potentially less relevant for recent climate studies.
• The dataset's last update was in 1988, indicating it may not reflect the latest methodological standards or corrections.
