Mt. Laguna Tree Ring Chronology from 290 BC to 45 AD

Tree ring parameters from the Mt. Laguna site in California, United States, cover a period from 290 to -45 calendar years before present. The data is archived by NOAA's National Centers for Environmental Information under its Paleoclimatology World Data Service. This study was last updated in 1995.

Use Cases

• Analyze annual tree ring width variations to reconstruct past climate conditions like precipitation or temperature.
• Calibrate the chronology with other proxy records using the calendar years before present (BP) time scale.
• Study long-term environmental changes in Southern California forests using site-specific parameters.

Strengths

• Time period coverage spans 335 calendar years, from 290 to -45 BP.
• Data is from an authoritative source, NOAA NCEI's World Data Service for Paleoclimatology.

Limitations

• Data is temporally stale, last updated in 1995.
• Specific row count, column names, and sample data are unavailable for assessment.
• Geographic coverage is limited to a single site in California.
