416 to -48 calendar years before present (BP) of tree ring data from Douglas Fir (PSME) trees at Valley View Ranch, Colorado. The dataset is archived by NOAA's National Centers for Environmental Information as part of its Paleoclimatology World Data Service. This study was last updated in 1998.
Use Cases
- Reconstruct annual climate variables like precipitation or temperature from tree ring width measurements.
- Calibrate climate models using the 464-year chronology spanning 416 to -48 BP.
- Analyze growth patterns of Pseudotsuga menziesii (PSME) in a specific Colorado location for ecological studies.
- Compare this local chronology with other regional tree ring datasets to identify broader climate signals.
Strengths
- Time series covers 464 calendar years (416 to -48 BP).
- Data is curated and archived by the authoritative NOAA NCEI Paleoclimatology program.
- Includes specific species (PSME) and location (Valley View Ranch, Colorado) metadata.
Limitations
- Data is temporally stale, with a last update recorded in 1998.
- Sample size (number of tree cores or rows) is unknown, limiting statistical assessment.
- Geographic coverage is limited to a single ranch site in Colorado.
