Kamiak Butte Ponderosa Pine Tree Ring Chronology from 137 BC

137 calendar years before present of tree ring data from Ponderosa Pine trees at Kamiak Butte, Washington. The dataset is archived by NOAA's National Centers for Environmental Information under its Paleoclimatology World Data Service. The study was last updated in 1975.

Use Cases

• Reconstruct annual precipitation or temperature anomalies using tree-ring width measurements.
• Calibrate regional climate models by comparing the Kamiak Butte chronology with other Pacific Northwest tree-ring series.
• Analyze forest growth response to historical climate events over the 137-year period.
• Establish a baseline historical growth pattern for Ponderosa Pine (PIPO) in eastern Washington.

Strengths

• Provides a 137-year chronology from calendar years 137 to -25 BP.
• Data originates from the authoritative NOAA/NCEI World Data Service for Paleoclimatology.
• Focuses on a specific species (Ponderosa Pine) and location (Kamiak Butte, Washington).

Limitations

• The dataset's last update was in 1975, indicating it is a historical archive with no recent additions.
• The exact number of tree samples, core measurements, and derived parameters are unknown.
• Geographic coverage is limited to a single butte in Washington state.
