Crater Lake Tree Ring Chronology From 260 to 42 BC

NOAA/WDS Paleoclimatology archives a tree ring chronology from the Crater Lake East Medium site in Oregon, USA. The dataset provides parameters for reconstructing past climate conditions, covering the period from 260 to 42 years before present. It is maintained by the NOAA National Centers for Environmental Information.

Use Cases

• Reconstruct past temperature or precipitation using tree ring width parameters.
• Calibrate climate models by comparing the chronology with other proxy records from the region.
• Analyze growth patterns in Tsuga mertensiana (TSME) trees for ecological studies.
• Establish a dated timeline for environmental events in Oregon using the provided calendar years before present.

Strengths

• Time series covers a 218-year period (260 to 42 BP).
• Data is curated and archived by the authoritative NOAA National Centers for Environmental Information.

Limitations

• Data is temporally stale, last updated in 1992.
• Sample size and specific row count for tree ring measurements are unknown.
• Geographic scope is limited to a single site in Oregon.
