Tree Ring Chronology from Alcova Reservoir Site B in Wyoming

NOAA/WDS Paleoclimatology archives a tree-ring chronology for the Alcova Reservoir Site B, featuring Ponderosa Pine (PIPO) data. The record covers 202 calendar years, from 188 to -14 years before present. NOAA National Centers for Environmental Information (NCEI) produced and maintains this dataset, which was last updated in 1964.

Use Cases

• Reconstruct past climate variables like precipitation from tree-ring width measurements.
• Calibrate and validate climate models using the 202-year proxy record.
• Analyze growth anomalies in the Ponderosa Pine chronology to identify drought events.
• Compare this site's chronology with other ITRDB records for regional climate signal analysis.

Strengths

• 202-year temporal coverage provides a multi-century climate proxy.
• Data is curated and archived by the authoritative NOAA NCEI World Data Service.

Limitations

• The dataset's last update was in 1964, indicating it is a static historical archive with no recent additions.
• Specific metrics like sample depth, replication, or measurement statistics are unknown from the provided description.
