Swiss Tree Ring Chronology from 230 to -44 BP

274 calendar years of tree ring data from La Rolaz, Switzerland, provide a paleoclimate record. The dataset was archived by NOAA National Centers for Environmental Information under its World Data Service for Paleoclimatology. It was last updated in 1994.

Use Cases

• Reconstruct past climate variables like temperature or precipitation using tree ring width measurements.
• Calibrate and validate climate models for the Alpine region with a 274-year proxy record.
• Analyze the frequency of extreme growth years as indicators of historical environmental stress events.
• Compare this Swiss chronology with other European tree ring datasets to assess spatial climate patterns.

Strengths

• Covers a specific 274-year time period from 230 to -44 calendar years BP.
• Geographically precise data from a single location in Switzerland, Western Europe.

Limitations

• The dataset is temporally stale, with a last update date of 1994.
• The sample size, row count, and specific measured parameters are unknown.
