Spanish Tree Ring Chronology from Gredos Mountains (181 to -35 BP)

Tree ring width measurements from the Gredos Navarredonda site in Spain, used for paleoclimate reconstruction. The chronology covers the period from 181 to -35 calendar years before present. Data is archived by NOAA's National Centers for Environmental Information World Data Service for Paleoclimatology and was last updated in 1985.

Use Cases

• Reconstruct past temperature or precipitation anomalies for Spain using the tree ring width time-series.
• Calibrate the chronology against other regional proxy records using its calendar year dating.
• Analyze growth patterns and climate sensitivity for the Pinus sylvestris (PISY) species at the Gredos site.
• Study decadal to centennial-scale climate variability in Southern Europe during the covered time period.

Strengths

• Chronology spans 216 years (181 to -35 BP), providing multi-century coverage.
• Data is curated and archived by the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Data is temporally stale, with a last update date of 1985, potentially missing newer methodological refinements.
• Geographic scope is limited to a single site (Gredos Navarredonda) in Spain.
