Westney Farmstead Barn Tree Ring Chronology from New Zealand

Tree ring data from a single site in New Zealand provides a paleoclimate record. The chronology spans 346 years, from 435 to 89 calendar years before present. The data is archived by NOAA's National Centers for Environmental Information.

Use Cases

• Analyzing annual tree ring width variations to reconstruct past climate conditions like temperature or precipitation.
• Crossdating the site chronology with other regional tree ring series to validate the time period coverage from 435 to 89 BP.
• Calibrating the tree ring proxy data against instrumental climate records for the geographic location of New Zealand.

Strengths

• Time period coverage spans 346 calendar years.
• Data originates from NOAA NCEI, a authoritative paleoclimate archive.

Limitations

• Data is from a single site (Westney Farmstead Barn), limiting regional representativeness.
• The temporal coverage ends at 89 BP, which may not overlap with modern instrumental records.
