Larch Valley Young Tree Ring Chronology from Alberta

NOAA/WDS Paleoclimatology archives a tree-ring chronology dataset from young trees in Larch Valley, Alberta, Canada. The data covers a 93-year period from 57 to -36 calendar years before present. The National Centers for Environmental Information (NCEI) compiled and published this study, with a last update recorded in 1986.

Use Cases

• Reconstruct past climate variables like temperature or precipitation using annual tree-ring width measurements.
• Calibrate climate models by comparing the tree-ring chronology with instrumental records for the region.
• Study the growth response of young Larch trees to environmental stressors documented in the ring series.
• Analyze the frequency of narrow rings, indicative of past drought events or cold periods, within the chronology.

Strengths

• Data spans a 93-year period (57 to -36 BP), providing a multi-decadal environmental record.
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• The dataset's last update was in 1986, making it temporally stale for contemporary climate studies.
• Specific sample size (number of trees/cores), measurement parameters, and geographic coordinates are not detailed in the provided description.
