NOAA/WDS Paleoclimatology provides a tree-ring chronology from Los Alamos, New Mexico, for the species PSME (Pinus strobiformis). The data covers the period from 269 to -19 calendar years before present (BP), archived by the NOAA National Centers for Environmental Information. This study is part of the International Tree-Ring Data Bank (ITRDB) collection.
Use Cases
- Reconstruct past climate variables like temperature or precipitation using the annual tree-ring width series.
- Calibrate climate models by comparing the PSME tree-ring chronology with instrumental records for the New Mexico region.
- Analyze long-term ecological responses to climate change by examining growth trends in the Pinus strobiformis species over the 288-year period.
Strengths
- Data spans 288 calendar years (269 to -19 BP), providing a multi-century climate proxy.
- Archived and standardized as part of the International Tree-Ring Data Bank (ITRDB), ensuring methodological consistency.
Limitations
- The temporal coverage ends at -19 BP (approximately 1970 CE), making the record potentially stale for recent climate analysis.
- Geographic scope is limited to a single site (Los Alamos, New Mexico), limiting regional representativeness.
