Tree ring width measurements from the Zuun Mod site in Mongolia provide a 414-year climate proxy record. The data, archived by NOAA's World Data Service for Paleoclimatology, was published in 1996. It represents a foundational dendrochronological study for Eastern Asia.
Use Cases
- Reconstruct past temperature or precipitation anomalies in Mongolia using the annual tree ring width time-series.
- Calibrate the Zuun Mod tree ring chronology against other regional paleoclimate records for cross-validation.
- Analyze the frequency of narrow rings (indicating stress years) within the 414-year sequence to identify historical drought periods.
Strengths
- Covers a substantial 414-year time period (368 to 46 BCE).
- Sourced from the authoritative NOAA/NCEI World Data Service for Paleoclimatology.
- Provides a geographically specific record for a key region in Eastern Asia.
Limitations
- The dataset is temporally stale, with a last documented update in 1996.
- The exact sample size (number of tree cores) and replication statistics are unknown.
- Geographic coverage is limited to a single site (Zuun Mod) in Mongolia.
