Northwest China 540-Year Tree Ring Chronologies for Paleoclimate Study

Tree ring chronologies from Northwest China provide a 540-year paleoclimate record. The data covers the period from 496 to -43 calendar years before present. NOAA National Centers for Environmental Information (NCEI) archives this study, which was last updated in 1993.

Use Cases

• Reconstructing past temperature or precipitation using tree ring width and density parameters.
• Analyzing climate periodicity and extreme events over a 540-year time series from Northwest China.
• Calibrating climate models with proxy data from the specific geographic location of Eastern Asia.

Strengths

• 540-year continuous time series for long-term climate analysis.
• Data archived by the authoritative NOAA National Centers for Environmental Information (NCEI).

Limitations

• Data is temporally stale, with a last update recorded in 1993.
• Specific parameters, sample size, and measurement methods are not detailed in the provided description.
