Rio Blanco Jujuy Tree Ring Chronology for Climate Reconstruction

NOAA's World Data Service for Paleoclimatology archives this tree ring dataset from Rio Blanco, Jujuy, Argentina. The chronology covers 131 calendar years, from 100 to -31 years before present. NOAA National Centers for Environmental Information (NCEI) published the data in 1981.

Use Cases

• Reconstruct historical temperature or precipitation patterns using annual tree ring width measurements.
• Calibrate climate models by comparing the tree ring chronology with other regional paleoclimate proxies.
• Analyze climate extremes and variability over the 131-year period recorded in the Rio Blanco chronology.

Strengths

• Data originates from NOAA's authoritative World Data Service for Paleoclimatology.
• Provides a 131-year continuous chronology for climate reconstruction.

Limitations

• Data is temporally stale, last updated in 1981.
• The specific tree ring parameters and measurement methods are not detailed in the provided description.
• Geographic coverage is limited to a single site in Argentina.
