Tree Ring Chronology from Telephone Draw South, Oregon (508 to -45 BP)

NOAA's World Data Service for Paleoclimatology archives a tree-ring chronology for the Telephone Draw South site in Oregon, USA. The dataset provides paleoclimate proxy data covering a 553-year period from 508 to -45 calendar years before present. It was published by NOAA National Centers for Environmental Information in 1995.

Use Cases

• Reconstruct annual temperature or precipitation anomalies from the tree-ring width parameter for the Pacific Northwest region.
• Calibrate climate models using the high-resolution, annually-resolved proxy data spanning over five centuries.
• Analyze growth patterns in Pinus ponderosa (PIPO) trees from the ITRDB site OR057 to study ecological responses to past climatic events.
• Compare the chronology from the Telephone Draw South geographic location with other regional tree-ring records to identify spatial climate patterns.

Strengths

• Covers a 553-year time period (508 to -45 BP), providing a multi-century climate record.
• Data is curated and archived by the authoritative NOAA National Centers for Environmental Information (NCEI).

Limitations

• Temporal coverage ends at -45 BP (approximately 1995 CE), with no updates since the 1995 publication date.
• Specific sample depth, measurement parameters (e.g., ring width, density), and quality metrics are not detailed in the provided metadata.
