Tree ring width measurements from Nojabrsk, Russia, provide a 144-year climate proxy record from 100 to -44 calendar years before present. The dataset is part of the NOAA NCEI World Data Service for Paleoclimatology archives, contributed by researcher Schweingruber. This specific chronology was last updated in the archive in 1994.
Use Cases
- Reconstruct past temperature and precipitation anomalies by calibrating tree ring width series against modern instrumental records.
- Analyze growth response and resilience of Siberian trees to historical climate events within the recorded time window.
- Cross-date and validate other paleoclimate proxy records from Eastern Europe using the established tree ring chronology.
Strengths
- Data covers a specific 144-year time period (100 to -44 BP).
- Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.
- Includes precise geographic location information for the sampling site in Russia.
Limitations
- The dataset is temporally stale, with a last known update in 1994.
- Sample size (number of trees/cores) and specific measurement parameters are unknown from the description.
- The time coverage is relatively short (144 years) compared to many millennial-length tree ring chronologies.
