Colorado Ponderosa Pine Tree Ring Chronology 280 BP to 37 BP

280 tree-ring width measurements from Ponderosa Pine (PIPO) near Horsetooth Reservoir, Colorado, covering the period from 280 to 37 calendar years before present. The dataset was archived by NOAA NCEI's World Data Service for Paleoclimatology and last updated in 1987.

Use Cases

• Reconstruct annual precipitation or temperature anomalies from tree-ring width chronologies.
• Calibrate tree-ring growth response to climate variables for the Ponderosa Pine species.
• Cross-date and validate other tree-ring chronologies from the Colorado Front Range region.
• Analyze long-term climate trends and extreme events over a 317-year period in the late Holocene.

Strengths

• 317-year continuous chronology from 280 to 37 BP
• Data archived and standardized by NOAA's authoritative World Data Service for Paleoclimatology

Limitations

• Dataset is temporally stale, last updated in 1987
• Limited geographic scope to a single site in Colorado
• Unknown sample depth (number of tree cores) used to build the chronology
