NOAA/WDS Paleoclimatology archives a tree-ring width dataset from Big Cypress State Park, Louisiana. The data provides a paleoclimate record covering the period from 750 to 37 calendar years before present. It was published by the NOAA National Centers for Environmental Information in 1987.
Use Cases
- Reconstruct past climate variables like temperature or precipitation by analyzing the tree-ring width time-series.
- Calibrate climate models using the high-resolution, annually-resolved proxy data from 750 to 37 BC.
- Study regional climate anomalies by comparing this Louisiana tree-ring record with other North American paleoclimate series.
Strengths
- Covers a 713-year time period (750 to 37 BC) for long-term trend analysis.
- Data is part of the authoritative PAGES North America 2K paleoclimate network.
Limitations
- Data is temporally stale, with a last recorded update in 1987.
- Sample size and replication depth of the tree-ring series are unknown from the description.
- Geographic coverage is limited to a single site in Louisiana.
