Australian Tree Ring Chronology From 105 to -23 BP

NOAA's National Centers for Environmental Information provides a tree-ring chronology for Australia, covering the period from 105 to -23 calendar years before present. The dataset is part of the World Data Service for Paleoclimatology and was archived by NOAA NCEI. The data was last updated in the system on January 1, 1973.

Use Cases

• Reconstructing past climate parameters like temperature or precipitation from tree-ring width measurements.
• Analyzing the temporal coverage from 105 to -23 BP to study climate trends and anomalies in ancient Australia.
• Calibrating regional climate models using the geographic location data specifying Australia as the study site.
• Comparing this tree-ring chronology with other paleoclimate proxies for multi-proxy climate reconstructions.

Strengths

• Temporal coverage spans 128 calendar years from 105 to -23 BP.
• Data is curated and archived by the authoritative NOAA National Centers for Environmental Information.

Limitations

• The dataset's last known update was in 1973, indicating potential staleness and lack of recent curation.
• Specific sample size, row count, and measurement parameters are not provided in the available metadata.
