Nepal Tree Ring Chronology from 223 to -47 BP

Tree ring width chronology data from the Deorali La site in Nepal, Southcentral Asia. The time series covers 270 calendar years, from 223 to -47 years before present (BP). This paleoclimatology study was archived by NOAA NCEI's World Data Service and last updated in 1997.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing the tree ring width chronology.
• Calibrate the chronology against other proxy records using the provided calendar year before present (BP) timeline.
• Study climate events in Southcentral Asia by examining growth patterns within the 270-year time span.

Strengths

• Data covers a specific 270-year time period (223 to -47 BP).
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.
• Geographic location is precisely defined as Nepal, Southcentral Asia.

Limitations

• Data is temporally stale, with a last recorded update in 1997.
• The sample size (number of tree cores or series) is unknown, limiting statistical assessment.
• Calendar year BP notation requires conversion for alignment with standard historical timelines.
