Idaho Tree-Ring Width Chronology from 450 to -30 BP

NOAA/WDS Paleoclimatology archives a tree-ring width chronology from the Upper Sandpass site in Idaho, USA. The dataset provides paleoclimate proxy data covering the period from 450 to -30 calendar years before present. It is maintained by NOAA National Centers for Environmental Information under the World Data Service for Paleoclimatology.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing the annual tree-ring width time-series.
• Calibrate climate models using the high-resolution proxy data from 450 to -30 BP for the Idaho region.
• Study regional climate extremes and their frequency by examining variance in the ring-width parameter over the 480-year period.
• Correlate this Idaho chronology with other North American 2K network tree-ring records to analyze spatial climate patterns.

Strengths

• Data covers a specific 480-year period (450 to -30 BP) for high-resolution temporal analysis.
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.
• Part of the structured PAGES North America 2K Version network, facilitating continental-scale comparison.

Limitations

• Temporal coverage ends at -30 BP, limiting direct analysis of the most recent two millennia.
• Sample size, replication, and site details are unknown without accessing full metadata.
• Geographic coverage is limited to a single site (Upper Sandpass, Idaho), reducing spatial representativeness.
