347 years of tree-ring width data from the Cuenca Una Site 1 in Spain provide a proxy for past climate conditions. The dataset is part of the International Tree-Ring Data Bank (ITRDB) and was archived by NOAA's National Centers for Environmental Information. This paleoclimate record was last updated in 1985.
Use Cases
- Reconstruct past temperature or precipitation using the PINI (Pinus nigra) tree-ring width chronology.
- Calibrate the tree-ring series against known climate events within the 312 to 35 BC time period.
- Analyze growth patterns in Pinus nigra to infer ecological stress events from the recorded ring widths.
- Compare this ITRDB SPAI045 chronology with other regional tree-ring datasets to validate climate reconstructions.
Strengths
- Covers a continuous 347-year period from 312 to 35 BC.
- Geographically specific to a single site in Spain, enabling localized climate analysis.
- Part of the authoritative International Tree-Ring Data Bank (ITRDB) collection.
Limitations
- Data is temporally stale, with a last update date of 1985, potentially missing modern reanalysis.
- The sample size (number of tree cores) and replication statistics are unknown, affecting confidence in the chronology.
- Limited to a single tree species (Pinus nigra) at one site, which may not represent broader regional climate.
