237 calendar years of tree ring data from a pine species (PSME) in California's Point Reyes Bear Valley area. The data was archived by NOAA's National Centers for Environmental Information and originates from a Paleoclimatology study. It was last updated in 1997.
Use Cases
- Analyze tree ring width variations over 237 years to infer past climate conditions.
- Correlate the dated tree ring chronology with other paleoclimate proxies for the region.
- Study the growth response of Pinus species (PSME) to environmental changes from 190 to -47 BP.
Strengths
- 237-year time series of tree ring parameters.
- Geographic location precisely defined as Point Reyes Bear Valley, California.
Limitations
- Data last updated in 1997, potentially lacking modern validation or integration.
- Limited to a single tree species (PSME) at one location, reducing generalizability.
- Unknown sample size (number of trees or cores analyzed).
