Horsetooth Reservoir Tree Ring Chronology for Colorado Paleoclimate

NOAA/WDS Paleoclimatology archives this tree ring dataset from the Horsetooth Reservoir C site in Colorado. It provides a chronology covering 314 years, from 300 to -14 calendar years before present, for reconstructing past climate conditions. The data is maintained by the NOAA National Centers for Environmental Information.

Use Cases

• Reconstruct annual temperature or precipitation anomalies from tree ring width measurements.
• Calibrate climate proxy models using the 314-year chronology for the Colorado region.
• Analyze growth patterns in Pinus ponderosa (PIPO) trees for dendroecological studies.
• Compare this ITRDB series (CO040) with other chronologies to assess regional climate signals.

Strengths

• 314-year chronology providing multi-century climate context.
• Data is archived and curated by the authoritative NOAA NCEI World Data Service.

Limitations

• Temporal coverage ends at -14 BP (1964 CE), lacking recent decades.
• Sample size and replication statistics for the tree ring series are unknown.
• Geographic scope is limited to a single site (Horsetooth Reservoir) in Colorado.
