Montana Tree Ring Chronology from 582 to -15 BP

582 to -15 calendar years before present of tree ring width measurements from a Pseudotsuga menziesii (Douglas fir) site in Montana, USA. The dataset is part of the NOAA/WDS Paleoclimatology archive and was contributed by researcher Ferguson. It is a tree ring chronology for climate reconstruction studies.

Use Cases

• Reconstructing historical temperature or precipitation anomalies from the tree ring width time-series.
• Calibrating climate models by comparing the proxy chronology with instrumental records for the region.
• Analyzing growth response and climate sensitivity of Pseudotsuga menziesii (PSME) over a ~600-year period.
• Investigating extreme climatic events, such as droughts, visible as narrow rings in the chronology.

Strengths

• Chronology covers approximately 600 years, from 582 to -15 BP.
• Data is curated and archived by the authoritative NOAA National Centers for Environmental Information (NCEI).

Limitations

• The dataset's last update was in 1965, indicating it is a static, historical archive and may not reflect modern analytical standards.
• Sample size, replication depth, and specific site details are unknown from the provided metadata.
