Moroccan Tree Ring Chronology from 584 to 37 BC

Tree ring width chronology data provides a climate proxy record for Northern Africa. The time series covers 621 years, from 584 to 37 BC (calendar years before present). This archived paleoclimatology study was published by NOAA National Centers for Environmental Information in 1987.

Use Cases

• Reconstruct past drought indices by analyzing annual tree ring width variations.
• Calibrate climate models using the 621-year proxy record of environmental conditions.
• Study regional climate teleconnections by comparing this Moroccan chronology with other tree ring datasets.
• Investigate growth anomalies in the ring width series as potential indicators of volcanic or climatic events.

Strengths

• Time series spans 621 calendar years, providing a multi-century climate record.
• Data is archived and curated by NOAA's World Data Service for Paleoclimatology, an authoritative source.

Limitations

• Data is temporally stale, last updated in 1987 and may not reflect more recent methodological standards.
• Geographic coverage is limited to a single site in Morocco, reducing regional representativeness.
• Sample size (number of tree cores) and replication depth are unknown from the provided metadata.
