Spanish Tree Ring Chronology from 235 to -38 BP

273 calendar years of tree ring data from Spain provide parameters for paleoclimate reconstruction. The dataset is archived by NOAA's National Centers for Environmental Information under its World Data Service for Paleoclimatology. This specific study was last updated in 1988.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing tree ring width parameters over the 273-year chronology.
• Calibrate climate models for Southern Europe using the proxy data from the 'PISY' species (likely Pinus sylvestris).
• Study extreme climate events within the time period coverage from 235 to -38 BP using annual-resolution tree ring features.
• Compare this ITRDB series (SPAI021) with other regional chronologies to assess spatial climate patterns.

Strengths

• Covers 273 calendar years (235 to -38 BP) of annual-resolution data.
• Part of the authoritative International Tree-Ring Data Bank (ITRDB) collection curated by NOAA NCEI.

Limitations

• The dataset's last update was in 1988, making it temporally stale for contemporary analysis methods.
• Sample size and replication depth for the tree ring series are unknown, potentially limiting statistical robustness.
• Geographic coverage is limited to a single site in Spain, reducing generalizability.
