Tree Ring Chronology from Hump Lakes, British Columbia (76 to -48 BP)

NOAA/WDS Paleoclimatology archives a tree-ring chronology from the Hump Lakes area in British Columbia, Canada. The dataset provides parameters for dendroclimatological analysis, covering the period from 76 to -48 calendar years before present. It was published by NOAA National Centers for Environmental Information as part of the World Data Service for Paleoclimatology, with the record last updated in 1998.

Use Cases

• Reconstructing past temperature or precipitation levels using the tree-ring width parameter for the British Columbia region.
• Calibrating climate models by comparing the chronology data from 76 to -48 BP with other proxy records.
• Analyzing growth anomalies in the TSME (mountain hemlock) species to identify past environmental stress events.

Strengths

• Data is archived and curated by the authoritative NOAA National Centers for Environmental Information.
• Covers a specific 124-year time period (76 to -48 BP) for a defined geographic location.

Limitations

• Temporal coverage is limited to a short, ancient period (124 years around 0 BP).
• The dataset is temporally stale, with its last known update in 1998.
