Nepal Tree Ring Chronology from 209 to -29 BP

NOAA/WDS Paleoclimatology archives a tree ring dataset from the GhurchiLehk site in Nepal, Southcentral Asia. The chronology covers the period from 209 to -29 calendar years before present. This study is maintained by the NOAA National Centers for Environmental Information and was last updated in 1979.

Use Cases

• Reconstruct historical temperature or precipitation anomalies using the tree ring width chronology.
• Calibrate climate models by comparing the tree ring proxy data with known historical climate periods.
• Analyze growth patterns and climate sensitivity from the GhurchiLehk site tree ring parameters.
• Study long-term environmental changes in Southcentral Asia using the 238-year time series.

Strengths

• Time series spans 238 years, from 209 to -29 BP.
• Data is curated and archived by the authoritative NOAA National Centers for Environmental Information.

Limitations

• The dataset's last update was in 1979, indicating potential staleness relative to modern methods.
• Specific parameters, sample size, and measurement details are not provided in the available metadata.
