Colorado Ponderosa Pine Tree Ring Chronology From 340 to 14 BCE

Tree ring width measurements from Ponderosa Pine (PSME) in El Dorado Canyon, Colorado. The chronology spans 354 years, from 340 to 14 calendar years before present. The dataset was archived by NOAA NCEI's World Data Service for Paleoclimatology, with a last update recorded in 1964.

Use Cases

• Reconstruct past precipitation or temperature anomalies by analyzing annual tree ring width variations.
• Calibrate radiocarbon dating or validate other paleoclimate proxies using the established tree ring chronology.
• Study the growth response of Ponderosa Pine to historical environmental stressors within the specified 354-year period.

Strengths

• Chronology covers a specific 354-year period from 340 to 14 BCE.
• Data is curated and archived by the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Sample size and replication statistics for the underlying tree cores are unknown.
• Data is temporally stale, with a last update date of 1964, potentially lacking modern reanalysis.
• Geographic coverage is limited to a single site in El Dorado Canyon, Colorado.
