337 calendar years of tree ring data from the Tyn hill site in the Altai region of Russia, covering the period from 337 to 44 BC. This paleoclimatology study was archived by NOAA's National Centers for Environmental Information. The dataset was last updated in 1994.
Use Cases
- Reconstruct historical temperature or precipitation anomalies using annual tree ring width measurements.
- Calibrate climate models by comparing the tree ring chronology with other proxy records for the period 337-44 BC.
- Analyze growth patterns of Pinus sylvestris (PISY) trees in response to past environmental stressors.
- Establish a regional dendrochronological master chronology for the Altai mountains using the ITRDB RUSS131 series.
Strengths
- Covers a 381-year time series (337 to 44 BC), providing a multi-century climate record.
- Data is curated and archived by NOAA's World Data Service for Paleoclimatology, an authoritative source.
Limitations
- The dataset is temporally stale, with a last update date of 1994, potentially missing modern reanalysis or corrections.
- Geographic coverage is limited to a single site (Tyn hill), which may not be representative of broader regional climate.
