Nevada Tree Ring Width Chronology for Paleoclimate Analysis

Tree-ring width measurements from a single site in Nevada, USA, provide a 480-year climate proxy record. The data covers the period from 450 to -30 calendar years before present, archived by NOAA's World Data Service for Paleoclimatology. This collection is part of the PAGES North America 2K network for continental-scale climate reconstruction.

Use Cases

• Reconstruct past temperature or precipitation anomalies for Nevada using the tree-ring width time-series.
• Calibrate and validate regional climate model simulations for the last millennium against the 480-year proxy record.
• Analyze the frequency and magnitude of drought events in the western US by examining ring-width extremes.
• Contribute this site chronology to continental-scale syntheses like PAGES 2K by aligning its time-series with other proxy records.

Strengths

• Covers a 480-year time period (450 to -30 BP) for long-term trend analysis.
• Part of the authoritative PAGES North America 2K network, ensuring standardized quality.

Limitations

• Single-site chronology limits spatial representativeness for the broader Nevada region.
• Record ends at -30 BP (approximately 1980 CE), lacking recent decades for modern climate comparison.
• Unknown sample depth (number of trees/cores) affects uncertainty in the chronology.
