Schweingruber Tree Ring Chronology From Sarejmek, Kyrgyzstan

A 369-year tree ring chronology from the Sarejmek site in Kyrgyzstan, archived by the NOAA National Centers for Environmental Information. The data covers the period from 324 to -45 calendar years before present. This paleoclimatology study was last updated in 1995.

Use Cases

• Reconstruct past climate variables like temperature or precipitation using annual tree-ring width measurements.
• Calibrate and validate climate models by comparing the tree-ring proxy record with instrumental data for overlapping periods.
• Analyze long-term ecological trends and forest growth responses to historical environmental changes at the site.
• Cross-date and synchronize this chronology (ITRDB RUSS152) with other regional tree-ring datasets to improve climatic signal strength.

Strengths

• Chronology spans 369 years, providing a multi-century climate proxy.
• Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.

Limitations

• Data is temporally stale, with a last update date of 1995.
• The specific sample depth, measurement parameters, and potential biases are not detailed in the provided metadata.
• Geographic coverage is limited to a single site in Kyrgyzstan.
