A 444-year tree-ring chronology from Hovsgol Nuur, Mongolia, provides annual-resolution climate proxy data. The dataset, archived by NOAA's World Data Service for Paleoclimatology, covers the period from 400 to 44 calendar years before present. It was published as part of the International Tree-Ring Data Bank (ITRDB) in 1994.
Use Cases
- Reconstruct past temperature or precipitation anomalies using the annual tree-ring width series.
- Calibrate climate models by comparing the tree-ring chronology with instrumental records for the overlapping period.
- Analyze growth response and climate sensitivity of trees in the Mongolian region from the ring measurements.
- Study long-term ecological and climatic trends in Eastern Asia across the 444-year time span.
Strengths
- 444-year continuous annual-resolution chronology from 400 to 44 BP.
- Data is part of the authoritative NOAA/NCEI World Data Service for Paleoclimatology and ITRDB.
Limitations
- Temporal coverage ends at 44 BP, lacking recent centuries for modern climate comparison.
- Geographic scope is limited to a single site (Hovsgol Nuur) in Mongolia.
- Data publication date is 1994, indicating potential staleness in metadata and availability.
