NOAA NCEI archives this tree-ring chronology from the Ormes Peak site in Colorado, USA. The data covers a 270-year period from 236 to -34 calendar years before present. It was published by the NOAA World Data Service for Paleoclimatology.
Use Cases
- Reconstruct past climate variables like temperature or precipitation using tree-ring width measurements.
- Calibrate and validate climate models by comparing the chronology to instrumental climate records.
- Analyze growth patterns and extreme events recorded in the Ponderosa pine (PIPO) ring series.
- Establish a dated timeline for archaeological or geological studies in the Colorado region.
Strengths
- Data spans a 270-year period, providing a multi-century environmental record.
- Sourced from the authoritative NOAA World Data Service for Paleoclimatology.
Limitations
- Temporal coverage ends at -34 BP, making the most recent data approximately 34 years before 1950.
- The dataset is from a single site (Ormes Peak), limiting spatial representativeness.
