Los Alamos California Tree-Ring Chronology 140 to -34 BP

NOAA/WDS Paleoclimatology archives a tree-ring dataset from the Los Alamos, California site, identified as ITRDB CA622. The chronology provides annual-resolution data covering a period from 140 to -34 calendar years before present. This dataset was published by NOAA National Centers for Environmental Information in 1984.

Use Cases

• Reconstruct past temperature or precipitation in California using the annual tree-ring width series.
• Calibrate climate models by comparing the tree-ring chronology against instrumental climate records for the region.
• Analyze long-term climate trends and extreme events (e.g., droughts) encoded in the ring-width parameter.
• Study the response of local tree species to climate forcing over a 174-year period.

Strengths

• Data spans 174 years of annual-resolution climate proxy information.
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Dataset is temporally stale, with a last update date of 1984.
• Geographic coverage is limited to a single site (Los Alamos, California).
• Specific sample depth, measurement parameters, and potential missing years are unknown from the provided metadata.
