NOAA/WDS Paleoclimatology archives a tree ring chronology from Ostersund, Sweden. The data covers a 300-year period from 279 to -21 calendar years before present (BP). This dataset is maintained by the NOAA National Centers for Environmental Information.
Use Cases
- Reconstruct past temperature or precipitation anomalies using the tree ring width chronology.
- Calibrate climate models by comparing the proxy tree ring data with other paleoclimate records for the period 279-21 BP.
- Analyze growth patterns in Pinus sylvestris (PISY) trees from the Jämtland region for ecological studies.
- Establish a dated chronology for archaeological or geological events in Scandinavia using the tree ring series.
Strengths
- Data spans a 300-year period (279 to -21 BP), providing a multi-century climate proxy.
- Archived by the authoritative NOAA National Centers for Environmental Information (NCEI) under the World Data Service.
Limitations
- The temporal coverage is relatively short (300 years) compared to other paleoclimate records spanning millennia.
- Data is geographically limited to a single site (Ostersund, Sweden), reducing regional representativeness.
- The dataset's last update date is 1971, indicating the core data is historical and may lack modern reanalysis.
