Hermit Lake Tree Ring Chronology from Colorado (902 to -33 BP)

902 calendar years of tree ring data from the Hermit Lake site in Colorado, USA, extending from 902 to -33 years before present. The dataset is archived by the NOAA National Centers for Environmental Information (NCEI) World Data Service for Paleoclimatology. This paleoclimatology study was last updated in 1983.

Use Cases

• Reconstruct past climate variables like temperature or precipitation using the tree ring width chronology.
• Calibrate and validate climate models by comparing the proxy data from this chronology with instrumental records.
• Analyze ecological responses to historical climate events by examining growth anomalies in the ring series.
• Establish a regional master chronology for cross-dating other tree ring samples from Colorado.

Strengths

• Covers a 935-year time period from 902 to -33 calendar years BP.
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Temporal coverage ends at -33 BP, lacking overlap with recent instrumental climate records.
• Data is specific to a single site (Hermit Lake), limiting regional representativeness.
• The dataset was last updated in 1983, potentially missing modern methodological refinements.
