Spanish Tree Ring Chronology from 365 to -35 BP

Tree ring width measurements from the Puerto Llano site in Spain provide a 400-year climate proxy record. The data, archived by NOAA NCEI's World Data Service for Paleoclimatology, was originally published in 1985. It supports reconstruction of past environmental conditions in Southern Europe.

Use Cases

• Calibrating regional climate models by correlating tree ring width variations with known historical temperature and precipitation records.
• Reconstructing past drought events in Southern Europe by analyzing sequences of narrow tree ring widths.
• Establishing a dated chronology for archaeological sites in the region by cross-referencing the tree ring pattern.
• Studying long-term forest growth responses to climate change across a 400-year pre-industrial baseline.

Strengths

• Covers a 400-year time period from 365 to -35 calendar years before present.
• Part of the authoritative NOAA NCEI and World Data Service for Paleoclimatology archive.
• Provides a precisely dated, annual-resolution proxy record for climate reconstruction.

Limitations

• Data is temporally stale, with a last documented update in 1985, potentially lacking modern reanalysis.
• Geographic coverage is limited to a single site (Puerto Llano, Spain), limiting regional generalizations.
• The raw measurement data and specific metadata parameters are not detailed in the provided description.
