Virginia Tree Ring Chronology from 170 to -28 BP

Tree ring data from Dale City, Virginia, spans 198 years, from 170 to -28 calendar years before present. The dataset was archived by NOAA's National Centers for Environmental Information under the World Data Service for Paleoclimatology. This paleoclimatology study was last updated in 1978.

Use Cases

• Calibrating regional climate models using the tree ring width chronology as a proxy for past temperature or precipitation.
• Analyzing growth anomaly years within the 198-year sequence to identify extreme historical climate events.
• Comparing this Virginia chronology with other ITRDB records to study spatial patterns of past climate variability.

Strengths

• Covers a 198-year time period (170 to -28 BP) from a single location.
• Archived by the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Data is temporally stale, with a last update date of 1978.
• The geographic coverage is limited to a single site in Virginia, USA.
• The sample size and replication depth of the underlying tree cores are unknown.
