NOAA/WDS Paleoclimatology archives a tree-ring chronology from the Ghorepani Pass in the Annapurna region of Nepal. The data provides a proxy climate record covering 238 years, from 210 to -28 calendar years before present. This study was contributed by Schweingruber and archived by NOAA's National Centers for Environmental Information.
Use Cases
- Calibrating climate models by comparing tree-ring width data with instrumental records for the Nepal region.
- Reconstructing past temperature or precipitation anomalies from the annual tree-ring chronology.
- Analyzing growth trends and extreme event signatures within the ring-width time series.
- Studying ecological responses to historical climate shifts using the dated tree-ring record.
Strengths
- Data spans a 238-year period (210 to -28 BP), providing a multi-century climate proxy.
- Sourced from a high-altitude, climatically sensitive location in the Annapurna range.
- Archived and standardized by NOAA's authoritative World Data Service for Paleoclimatology.
Limitations
- Temporal coverage is relatively short (238 years) compared to millennial-length tree-ring chronologies.
- Geographic scope is limited to a single pass in Nepal, limiting regional generalizations.
- Data is temporally stale, with a last updated date of 1978, potentially lacking modern reanalysis.
