Tree ring width measurements from a sag pond site in Maine, USA, used for paleoclimate reconstruction. The chronology covers a 312-year period from 276 to -36 calendar years before present. Data is archived by NOAA's National Centers for Environmental Information under its World Data Service for Paleoclimatology.
Use Cases
- Reconstruct past temperature or precipitation anomalies by analyzing the tree ring width chronology.
- Calibrate climate models using the high-resolution, annually resolved proxy data from the time series.
- Study ecological responses to historical climate events by examining growth patterns in the ring record.
- Perform cross-dating with other regional tree ring chronologies using the shared time period coverage.
Strengths
- Covers a 312-year time period (276 to -36 BP) for climate analysis.
- Data is curated and archived by the authoritative NOAA NCEI World Data Service for Paleoclimatology.
Limitations
- Dataset is temporally stale, with a last update recorded in 1986.
- Geographic scope is limited to a single site (sag pond) in Maine, USA.
- Specific parameters, sample depth, and measurement statistics are not provided in the basic description.
