Nepalese Tree Ring Chronology from 278 to 46 BCE

NOAA's World Data Service for Paleoclimatology archives this tree ring dataset from the Nehe Karka site in Nepal, Southcentral Asia. The chronology covers a 324-year period from 278 to 46 calendar years before present. It was published by the NOAA National Centers for Environmental Information in 1996.

Use Cases

• Reconstruct historical climate variables like temperature or precipitation using tree ring width measurements.
• Calibrate regional climate models by comparing the tree ring chronology with known historical climate periods.
• Analyze growth patterns and environmental stressors recorded in the tree ring parameters for the specified time span.
• Establish a dated tree ring chronology for the Southcentral Asia region to support cross-site climate studies.

Strengths

• Data spans a 324-year period (278 to 46 BP), providing a multi-century record.
• Sourced from the authoritative NOAA/NCEI World Data Service for Paleoclimatology.
• Geographic location is precisely specified as Nepal, Southcentral Asia.

Limitations

• The dataset was last updated in 1996, indicating potential staleness and lack of recent curation.
• Specific parameters, sample size (row count), and file formats are not detailed in the provided metadata.
• Temporal coverage ends at 46 BP, limiting analysis of more recent centuries.
