Tree ring width measurements from Ponderosa Pine (PIPO) at the El Morro site in New Mexico. The chronology spans 436 years, from 414 to -22 calendar years before present. Data is archived by the NOAA National Centers for Environmental Information under its Paleoclimatology program.
Use Cases
- Reconstruct past climate variables like precipitation by analyzing annual tree ring width variations.
- Calibrate and validate climate models using the 436-year proxy record of environmental conditions.
- Study the growth response of Ponderosa Pine to historical environmental stressors at the El Morro site.
- Establish a dated chronology for archaeological or geological studies in the New Mexico region.
Strengths
- Chronology provides a 436-year continuous proxy record for climate analysis.
- Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.
Limitations
- Temporal coverage ends at -22 BP (approximately 1972 CE), with no recent updates.
- Geographic scope is limited to a single tree species at one site in New Mexico.
