A 313-year tree-ring chronology from Nepal, Southcentral Asia, covering the period from 267 to 46 BCE. The dataset contains parameters related to tree-ring growth and is archived by the NOAA National Centers for Environmental Information under its Paleoclimatology program. The data was last updated in the NOAA system in 1996.
Use Cases
- Reconstructing historical climate variables like temperature or precipitation using the tree-ring width or density parameters.
- Calibrating climate models for Southcentral Asia by comparing the tree-ring chronology against known historical climate events.
- Analyzing long-term ecological trends and forest growth patterns in Nepal from the provided tree-ring parameters.
Strengths
- Covers a specific 313-year period (267 to 46 BCE) for climate proxy analysis.
- Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.
Limitations
- Temporal coverage ends over 2000 years ago, limiting analysis of recent climate trends.
- Data last updated in 1996, potentially missing modern metadata standards or reanalysis.
- Geographic scope is limited to a single location in Nepal, reducing regional generalizability.
