Nepalese Tree-Ring Chronology for Paleoclimate Reconstruction

Tree-ring width measurements from the Lamjura site in Nepal, Southcentral Asia. The chronology covers 179 years, from 150 to -29 calendar years before present. Data is archived by NOAA's World Data Service for Paleoclimatology and was last updated in 1979.

Use Cases

• Calibrating climate models using the 179-year tree-ring chronology as a proxy for past temperature or precipitation.
• Analyzing growth anomaly patterns within the ring-width series to identify extreme historical climate events.
• Cross-dating this chronology with other regional tree-ring records to validate and extend climate reconstructions.
• Investigating the relationship between tree-ring parameters and specific climatic drivers documented in the metadata.

Strengths

• Chronology spans 179 calendar years, providing a multi-century environmental record.
• Data is curated and archived by NOAA's authoritative World Data Service for Paleoclimatology.

Limitations

• Temporal coverage ends at 29 years before present, limiting analysis of very recent climate trends.
• Data is from a single geographic site (Nepal), which may not represent broader regional patterns.
• The dataset was last updated in 1979, and newer methodologies or recalibrations may not be reflected.
