Washington Douglas Fir Tree Ring Chronology from Lava Beds

Tree ring data from Douglas Fir (PSME) specimens collected at Lava Beds in Washington state, USA, spans 579 years from 553 to -26 calendar years before present (BP). The data is archived by NOAA's National Centers for Environmental Information under its Paleoclimatology World Data Service. The study was published in 1976.

Use Cases

• Reconstruct annual climate variables like temperature or precipitation using the tree ring width series.
• Analyze growth patterns and anomalies within the 579-year chronology to identify past environmental events.
• Cross-date the PSME chronology with other regional tree ring datasets to validate climate reconstructions.
• Study the response of Douglas Fir to climatic changes over a multi-century period in Washington.

Strengths

• Data covers a 579-year time series from 553 to -26 BP.
• Specific geographic location (Washington, USA) and species (Douglas Fir, PSME) are documented.
• Data is curated and archived by NOAA NCEI, an authoritative environmental data agency.

Limitations

• The dataset is temporally stale, with a last updated date of 1976.
• The exact number of tree cores, measurement parameters, and data rows is unknown.
• Coverage ends 26 years before present, limiting analysis of the most recent historical period.
