Tierra del Fuego Tree Ring Paleoclimate Data

Tree ring data from Aserradero Isla Grande in Tierra del Fuego, Argentina, covering a period from 284 to -36 calendar years before present. The dataset is archived by the NOAA National Centers for Environmental Information under its Paleoclimatology World Data Service. The data was published in 1986.

Use Cases

• Reconstruct past climate variables like temperature or precipitation using tree ring width measurements.
• Analyze long-term climate trends in Tierra del Fuego over a 320-year period.
• Compare Southern Hemisphere paleoclimate records with other tree ring chronologies.
• Validate climate model simulations for historical periods using proxy data from tree rings.

Strengths

• Data spans a 320-year period (284 to -36 BP).
• Provided by NOAA NCEI, an authoritative environmental data agency.

Limitations

• Data is from a single site (Aserradero Isla Grande), limiting regional representativeness.
• The dataset was last updated in 1986, indicating potential staleness in metadata or processing methods.
• Specific parameters and measurement details are only available in the metadata, which must be consulted.
