Emerald Peak Tree Ring Chronology From 198 To -39 BP

237-year tree-ring chronology from the Emerald Peak site in Arizona's Pinaleno Mountains, covering the period from 198 to -39 calendar years before present. The dataset contains parameters related to tree ring growth, specifically from the ABLA (Abies lasiocarpa) species, and is archived by NOAA's World Data Service for Paleoclimatology. This study was published by Grissino-Mayer and last updated in 1989.

Use Cases

• Reconstructing past climate conditions, such as temperature or precipitation, by analyzing the tree-ring width series.
• Calibrating radiocarbon dating or other chronological models using the dated tree-ring sequence.
• Studying the growth response of Abies lasiocarpa (ABLA) to environmental stressors over a 237-year period.
• Comparing this site's chronology with others in the ITRDB (International Tree-Ring Data Bank) to analyze regional climate signals.

Strengths

• 237-year continuous chronology providing a long-term environmental record.
• Data is part of the authoritative NOAA/NCEI World Data Service for Paleoclimatology archive.
• Specific geographic location (Emerald Peak, Pinaleno Mountains, Arizona) and species (ABLA) are documented.

Limitations

• The dataset's last update was in 1989, making it temporally stale for contemporary analysis methods.
• The exact number of tree cores, sample depth, and measurement parameters are unknown from the provided description.
• Geographic coverage is limited to a single site in Arizona, which may not be representative of broader regions.
