Tree Ring Chronology from Dique Escaba in Tucuman, Argentina

NOAA's World Data Service for Paleoclimatology archives this tree ring chronology from the Dique Escaba site in Tucuman, Argentina. The data covers a 172-year period from 137 to -35 calendar years before present, used for climate reconstruction. The dataset was contributed by researcher Villalba and last updated in the NOAA archive in 1985.

Use Cases

• Reconstructing historical temperature or precipitation patterns for the Tucuman region using the tree ring width chronology.
• Calibrating climate models by comparing the proxy tree ring data from 137 to -35 BP with other paleoclimate records.
• Analyzing climate anomalies or extreme events within the 172-year time series captured in the tree ring parameters.
• Studying the growth response of tree species in Argentina to past environmental conditions recorded in the ring data.

Strengths

• Data spans a continuous 172-year period (137 to -35 BP), providing a multi-century climate proxy.
• Archived and maintained by the authoritative NOAA National Centers for Environmental Information (NCEI).
• Includes specific geographic location details for the Dique Escaba site in Tucuman, Argentina.

Limitations

• Temporal coverage is relatively short (172 years) compared to other paleoclimate proxy records.
• Dataset was last updated in the archive in 1985, indicating it is a static, legacy collection.
• Specific parameters, measurement units, and sample depth (number of tree cores) are not detailed in the provided metadata.
