NOAA/WDS Paleoclimatology provides a tree ring chronology from the Husband Lake site in Oregon, USA. The dataset covers a 471-year period from 431 to -40 calendar years before present. This archived study is maintained by the NOAA National Centers for Environmental Information.
Use Cases
- Reconstruct past climate variables like temperature or precipitation using the tree ring width series.
- Calibrate and validate climate models by comparing the tree ring proxy record with instrumental data.
- Analyze growth anomalies in the ring width data to identify past extreme climate events or disturbances.
- Establish a dated chronology for the TSME (mountain hemlock) species at this site for regional comparison.
Strengths
- Covers a 471-year time period (431 to -40 BP), providing a multi-century paleoclimate record.
- Archived and curated by the authoritative NOAA National Centers for Environmental Information (NCEI).
Limitations
- Temporal coverage ends at -40 BP (approximately 1990 AD), lacking recent decades of data.
- Geographic scope is limited to a single site (Husband Lake) in Oregon, USA.
- Specific parameters, measurement methods, and sample depth (number of cores) are not detailed in the provided description.
