Tree Ring Width Chronology from Indian Garden, Nevada (450 to -30 BP)

NOAA/WDS Paleoclimatology archives a tree-ring width chronology from the Indian Garden site in Nevada, USA. The data provides a proxy climate record spanning from 450 to -30 calendar years before present. This study is part of the PAGES North America 2K network and was published by the NOAA National Centers for Environmental Information.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree-ring width time-series as a proxy.
• Calibrate the chronology against other regional paleoclimate records from the PAGES 2K network.
• Analyze growth trends and extreme events (e.g., droughts) captured in the ring-width parameter.
• Validate climate model simulations of the past 500 years for the southwestern United States.

Strengths

• Chronology covers a 480-year period from 450 to -30 BP.
• Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.
• Part of the standardized PAGES North America 2K version, facilitating multi-proxy comparisons.

Limitations

• Temporal coverage ends at -30 BP (approximately 1980 CE), lacking recent decades.
• Geographic scope is limited to a single site (Indian Garden, Nevada).
• Sample size and replication depth of the underlying tree cores are unknown.
