Missouri Tree Ring Chronology from Lower Rock Creek

Tree ring width measurements from Lower Rock Creek, Missouri, provide a climate proxy record. The chronology spans 254 years, from 222 to -32 calendar years before present. Data was archived by NOAA's National Centers for Environmental Information in 1982.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing annual tree ring width variations.
• Calibrate climate models using the 254-year tree ring chronology as a proxy for pre-instrumental climate conditions.
• Cross-date tree ring sequences from other Missouri sites using this established Lower Rock Creek chronology.
• Study the response of tree growth to specific historical climate events recorded in the ring width series.

Strengths

• Data covers a 254-year time series from 222 to -32 BP.
• Sourced from the authoritative NOAA/NCEI World Data Service for Paleoclimatology.

Limitations

• Temporal coverage is limited to a specific 254-year period, not continuous to present.
• Geographic scope is restricted to a single site in Missouri, limiting regional generalizability.
• Data was last updated in 1982, potentially lacking modern reanalysis or updated metadata.
