Alaskan Alpine Tree Ring Chronology from 528 to -22 BP

528 to -22 calendar years before present (BP) of tree ring data from an alpine site in Alaska, United States. This paleoclimatology study is part of the NOAA/WDS Tree Ring collection, archived by the NOAA National Centers for Environmental Information. The data was last updated in the platform in 1972.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree ring width chronology.
• Calibrate climate models by comparing the tree ring proxy data with instrumental records for the region.
• Analyze growth response and climate sensitivity of Tsuga heterophylla (TSHE) in alpine environments.
• Study long-term ecological trends and disturbance events, such as volcanic eruptions, recorded in the ring sequences.

Strengths

• Time series spans approximately 550 years, from 528 to -22 calendar years BP.
• Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.

Limitations

• The dataset's last platform update was in 1972, indicating potential staleness in metadata or access methods.
• Specific sample size, measurement parameters, and geographic coordinates are not detailed in the provided description.
