Niwot Ridge Tree Ring Chronology For Paleoclimate Reconstruction

NOAA/WDS Paleoclimatology archives a tree-ring chronology dataset from Niwot Ridge, Colorado. The data covers 288 years, from 256 to -32 calendar years before present (BP), for dendroclimatic analysis. This archived study was last updated in 1982.

Use Cases

• Reconstruct past temperature or precipitation using annual tree-ring width measurements.
• Calibrate climate models by comparing the tree-ring chronology with other proxy records for the period 256 to -32 BP.
• Analyze growth anomalies in the chronology to identify extreme historical climate events.
• Study forest resilience and growth trends over a 288-year span at the Niwot Ridge site.

Strengths

• Covers a 288-year time period (256 to -32 BP) for climate trend analysis.
• Archived and maintained by the authoritative NOAA National Centers for Environmental Information (NCEI).

Limitations

• Data is temporally stale, with a last update recorded in 1982.
• Geographic scope is limited to a single site (Niwot Ridge, Colorado).
• The exact sample size (number of tree cores) and measurement parameters are not specified in the provided metadata.
