Black River Arizona Tree-Ring Chronology from 370 to -37 BP

NOAA/WDS Paleoclimatology archives a tree-ring chronology for Pseudotsuga menziesii (PSME) from the Black River site in Arizona. The data provides a proxy climate record spanning from 370 to -37 calendar years before present. This dataset was contributed by Graybill and is managed by the NOAA National Centers for Environmental Information.

Use Cases

• Reconstructing historical precipitation or temperature anomalies from tree-ring width measurements.
• Calibrating climate models by comparing the tree-ring proxy record with instrumental data for the region.
• Analyzing growth patterns in Pseudotsuga menziesii to study ecological responses to past climatic events.
• Establishing a dated chronology for archaeological or geological studies in Arizona using the provided time series.

Strengths

• Time series coverage spans 407 years (from 370 to -37 BP).
• Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.

Limitations

• The dataset's last update was in 1987, indicating it is a static archive and may not reflect newer methodologies.
• Specific parameters, measurement units, and sample depth are not detailed in the provided description.
