Nam Nao Tree Ring Chronology for Thai Paleoclimate

164 calendar years of tree ring data from Thailand, covering the period from 164 to -43 years before present. This paleoclimatology study is archived and provided by the NOAA National Centers for Environmental Information under the World Data Service for Paleoclimatology. The data was last updated in the NOAA system in 1993.

Use Cases

• Reconstruct past climate variables like temperature or precipitation using the tree ring width chronology.
• Calibrate the chronology against other regional proxy records to validate climate signals for the 164-year period.
• Analyze growth anomalies within the ring series to identify extreme historical climate events in Thailand.

Strengths

• Provides 164 calendar years of continuous proxy climate data.
• Sourced from the authoritative NOAA/NCEI World Data Service for Paleoclimatology.

Limitations

• Temporal coverage is limited to a specific 164-year window, which may not capture longer-term trends.
• Data is from a single geographic location (Thailand), limiting regional representativeness.
• The dataset's last known update was in 1993, indicating potential staleness in metadata or availability.
