Moroccan Tree Ring Chronology from 105 to -34 BP

NOAA/WDS Paleoclimatology archives a tree ring dataset from the Tazzeka region of Morocco. The chronology covers a 139-year period from 105 to -34 calendar years before present. This dataset is maintained by the NOAA National Centers for Environmental Information.

Use Cases

• Reconstruct past climate variables like temperature or precipitation using tree ring width parameters.
• Calibrate climate models for Northern Africa using the 139-year chronology.
• Analyze growth anomalies in the tree ring record to identify extreme historical climate events.
• Compare this Moroccan chronology with other regional tree ring datasets to study spatial climate patterns.

Strengths

• Data spans a 139-year period (105 to -34 BP), providing a multi-century climate record.
• Archived and curated by NOAA NCEI, an authoritative source for paleoclimate data.

Limitations

• The dataset's last documented update was in 1984, indicating potentially stale metadata or methods.
• Limited geographic scope to a single site (Tazzeka, Morocco), reducing regional representativeness.
• Unknown sample size and specific measurement parameters limit reproducibility without metadata review.
