Indian Tree Ring Chronology from Uttaranchal (239 BC to 38 AD)

239 calendar years of tree ring parameters provide a proxy climate record from Uttaranchal, India, spanning from 239 BC to 38 AD. The NOAA National Centers for Environmental Information archived this paleoclimatology study in 1988.

Use Cases

• Analyze tree ring width variations over the 239-year period to infer past climate conditions.
• Cross-reference the chronology with other ITRDB records using calendar years before present (BP) as a temporal join key.
• Validate climate model hindcasts for the Indian subcontinent using the proxy data from Uttaranchal.

Strengths

• Data spans 239 calendar years before present (239 to -38 BP).
• Part of the authoritative International Tree Ring Data Bank (ITRDB) collection.

Limitations

• Temporal coverage is limited to a specific 239-year period, not a continuous long-term record.
• Data originates from a single geographic location (Uttaranchal, India), limiting regional analysis.
• Last update was in 1988, indicating the data is static and may not reflect modern methodological standards.
