NOAA's World Data Service for Paleoclimatology archives this tree ring dataset for a Ponderosa Pine (PIPO) site at Eagle Rock, Colorado. The chronology provides annual climate proxy data covering a 596-year period from 549 to 47 BCE. The National Centers for Environmental Information (NCEI) published this record in 1997.
Use Cases
- Reconstruct annual temperature or precipitation anomalies for Colorado using the tree ring width chronology.
- Calibrate regional climate models by comparing the 596-year proxy record with instrumental data.
- Analyze growth patterns and climate sensitivity of Ponderosa Pine (PIPO) from the Eagle Rock site.
- Study long-term drought frequency and severity in the southwestern United States using the dated ring series.
Strengths
- Chronology spans a continuous 596-year period (549 to 47 BCE).
- Data is curated and archived by NOAA's authoritative World Data Service for Paleoclimatology.
Limitations
- Data has not been updated since its publication in 1997.
- Geographic scope is limited to a single tree species at one site in Colorado.
