Mount Graham Tree Ring Chronology from 254 to -40 BP

NOAA/WDS Paleoclimatology archives a tree ring dataset from the Pinaleno Mountains in Arizona. The chronology covers 294 years, from 254 to -40 calendar years before present. The data was published by NOAA National Centers for Environmental Information in 1990.

Use Cases

• Reconstruct past climate variables like temperature or precipitation using the tree ring width chronology.
• Calibrate the tree ring chronology against other paleoclimate proxies for the southwestern U.S. region.
• Analyze growth patterns in the Mount Graham site to study ecological responses to historical events.
• Validate climate model simulations for the period 254 to -40 BP using this proxy data series.

Strengths

• Time series covers a 294-year period (254 to -40 BP).
• Data is archived and curated by the authoritative NOAA National Centers for Environmental Information.

Limitations

• Dataset is temporally stale, last updated in 1990.
• Specific sample size, measurement parameters, and replication details are not provided in the metadata.
