Nepalese Tree Ring Chronology from 389 to -49 BP

NOAA/WDS Paleoclimatology archives a tree ring dataset from the Lamite Bhajyung site in Nepal. The chronology spans 438 years, from 389 to -49 calendar years before present. The National Centers for Environmental Information (NCEI) published this record in 1999.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree ring width chronology.
• Calibrate climate models by comparing the tree ring proxy data with instrumental records for the region.
• Analyze the frequency of extreme climatic events, such as droughts, indicated by narrow tree rings.
• Study ecological responses to climate change over a 438-year period using the annual resolution data.

Strengths

• Data covers a 438-year time period (389 to -49 BP).
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.
• Provides annual-resolution proxy data for climate reconstruction.

Limitations

• Temporal coverage ends 49 years before present (circa 1900 AD), limiting analysis of the 20th century.
• Geographic scope is limited to a single site (Lamite Bhajyung) in Nepal.
• Dataset metadata from 1999 may not reflect modern analytical standards or corrections.
