204-year tree ring chronology from the Col d'Allos site in the French Alps, spanning from 179 to -25 calendar years before present. The dataset was archived by NOAA's World Data Service for Paleoclimatology and is associated with the Schweingruber collection. This study type is classified as Tree Ring data for climate reconstruction.
Use Cases
- Reconstruct past summer temperatures using tree ring width (ABAL) measurements as a proxy.
- Calibrate climate models by comparing the annual resolution chronology with known historical climate events.
- Analyze growth anomaly years within the 204-year series to identify extreme climatic events like droughts or cold periods.
- Perform cross-dating with other European tree ring chronologies using the shared ITRDB code FRAN015.
Strengths
- Covers a 204-year chronology from 179 to -25 BP, providing a multi-century climate proxy.
- Part of the authoritative International Tree-Ring Data Bank (ITRDB) with code FRAN015, ensuring standardized format.
Limitations
- The dataset's temporal coverage ends at -25 BP (1975 CE), lacking modern extension for recent climate comparison.
- Sample size and replication depth for individual years are unknown, which could affect statistical confidence.
- Geographic scope is limited to a single alpine site (Col d'Allos), reducing regional representativeness.
