Nepal Tree Ring Chronology From 78 to 43 BC

78 to 43 BC tree ring data from Pun Hill, Nepal, archived by NOAA's World Data Service for Paleoclimatology. This study provides a chronology for reconstructing past climate conditions in Southcentral Asia. The dataset was published by NOAA NCEI in 1993.

Use Cases

• Reconstruct historical temperature or precipitation anomalies from the tree ring width chronology.
• Calibrate regional climate models using the 121-year chronology as a proxy record.
• Analyze long-term forest growth trends and ecological responses in Nepal from the ring parameters.
• Correlate this chronology with other regional tree ring datasets to study broader climate patterns.

Strengths

• 121-year continuous chronology from 78 to 43 BC.
• Geographically specific data from Pun Hill, Nepal.

Limitations

• Single geographic location limits regional representativeness.
• Data is from 1993 and may not reflect modern collection or standardization methods.
• Unknown sample size (number of trees/cores) underlying the chronology.
