78 to -44 calendar years before present (BP) of tree ring width data from a site in Maine, USA. The dataset is part of the NOAA/WDS Paleoclimatology archive, specifically for tree ring studies. It was archived by NOAA National Centers for Environmental Information (NCEI).
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 FRNI site.
- Study forest growth responses to historical climate events within the 122-year time period covered.
- Cross-date and validate other regional tree ring chronologies using the ITRDB ME027 series.
Strengths
- Data covers a 122-year time period (78 to -44 BP), providing a multi-decadal climate record.
- Archived within the authoritative NOAA/WDS Paleoclimatology system, ensuring standardized metadata.
- Part of the International Tree Ring Data Bank (ITRDB), facilitating comparative studies.
Limitations
- The dataset's last known update was in 1994, indicating potential staleness and lack of recent curation.
- Geographic coverage is limited to a single site (Portage, Maine), reducing regional representativeness.
- Specific sample depth (number of tree cores) and measurement statistics are unknown from the provided metadata.
