Hualapai Laguna Tank Tree Ring Chronology for Paleoclimate Study

NOAA/WDS Paleoclimatology archives a tree-ring chronology from a ponderosa pine site at Hualapai Laguna Tank in Arizona. The data covers a time period from 307 to -22 calendar years before present, providing a proxy climate record. This dataset was published by the NOAA National Centers for Environmental Information in 1972.

Use Cases

• Reconstruct past climate variables like precipitation or temperature from annual tree-ring width measurements.
• Calibrate and validate climate models using the multi-century proxy record provided by the chronology.
• Analyze the frequency and severity of historical drought events in Arizona using the ring-width time series.
• Study the growth response of ponderosa pine (PIPO) to environmental stressors over a 300+ year period.

Strengths

• Time series spans approximately 329 years (307 to -22 BP), offering a multi-century climate record.
• Data is curated and archived by the authoritative NOAA National Centers for Environmental Information.

Limitations

• Dataset is temporally stale, with a last update date recorded as 1972.
• Specific sample depth, measurement statistics, and site replication details are not provided in the input.
