South Dakota Tree Ring Chronology for Paleoclimate Analysis

A tree ring chronology from the Orland Hutterite Colony in South Dakota, United States, provides data for reconstructing past climate conditions. The dataset covers a period from 91 to -41 calendar years before present (BP) and is archived by NOAA's National Centers for Environmental Information. It was published as part of the World Data Service for Paleoclimatology in 1991.

Use Cases

• Reconstruct historical temperature or precipitation anomalies using the tree-ring width chronology.
• Calibrate climate proxy models by correlating ring-width indices with instrumental climate records for the region.
• Analyze climate extremes and variability during the covered period using the annual resolution time-series data.
• Compare this South Dakota chronology with other ITRDB (International Tree-Ring Data Bank) series for spatial climate pattern analysis.

Strengths

• Time-series spans 132 years (from 91 to -41 BP), providing multi-decadal climate context.
• Data is part of the authoritative International Tree-Ring Data Bank (ITRDB) collection, ensuring standardized formatting.

Limitations

• The dataset's temporal coverage ends 41 years after the present reference year (likely 1950), making the most recent data from approximately 1909 CE, which is over a century old.
• Specific parameters like ring width measurement values or site metadata are not detailed in the provided description, requiring access to full metadata.
