Colorado Tree Ring Chronology from 95 to -10 Years BP

Tree ring width measurements from a Colorado transect provide a climate proxy record covering 105 years, from 95 to -10 calendar years before present. The data is archived by the NOAA National Centers for Environmental Information under its World Data Service for Paleoclimatology. This specific chronology, identified as ITRDB CO045 for the PSME tree species, was last updated in the system in 1960.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing annual tree ring width variations.
• Calibrate climate models using the 105-year proxy record of environmental conditions from the Colorado transect.
• Study the growth response of PSME (Ponderosa Pine) to specific historical climate events captured in the ring series.
• Perform cross-dating analysis to validate and extend the tree ring chronology for the region.

Strengths

• Data covers a specific 105-year time period from 95 to -10 years BP.
• Sourced from the authoritative NOAA/NCEI World Data Service for Paleoclimatology.

Limitations

• Temporal coverage is relatively short for paleoclimate studies at 105 years.
• Data is geographically limited to a specific transect within Colorado.
• The last system update date is 1960, indicating potential staleness in metadata or availability.
