334 years of tree ring data from Ponderosa Pine in New Mexico, spanning from 297 to -37 calendar years before present. This paleoclimatology study was archived by NOAA's National Centers for Environmental Information. The dataset was last updated in 1987.
Use Cases
- Reconstruct past climate variables like precipitation or temperature using annual tree ring width measurements.
- Analyze long-term ecological growth patterns and disturbance events from the tree ring chronology.
- Calibrate and validate climate models for the southwestern US region using the 334-year proxy record.
- Study the frequency of extreme climatic events or droughts recorded in the ring width series.
Strengths
- 334-year continuous chronology from 297 to -37 BP.
- Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.
Limitations
- The dataset has not been updated since 1987, potentially missing modern analytical refinements.
- Specific measurement parameters, sample depth, and raw data columns are not detailed in the provided metadata.
- Geographic coverage is limited to a single site in New Mexico.
