Pollen-based quantitative mean annual precipitation reconstructions from the West Mediterr

Jon Camuera provides quantitative stacked mean annual precipitation reconstructions in millimeters per year for the West Mediterranean and West-Central African regions over the last 70,000 years. The data is derived from fossil pollen records using a Weighted Averaging-Partial Least Squares regression model and aggregates reconstructions from seven specific sediment cores. The dataset was last updated on 2026-04-09 and is associated with a 2025 research article in Communications Earth & Environment.

Use Cases

• Modeling long-term climate variability based on aggregated precipitation reconstructions from multiple sediment cores.
• Analyzing connections between Heinrich Stadials and regional precipitation patterns based on the described temporal coverage.
• Calibrating or validating climate models using quantitative mean annual precipitation data derived from fossil pollen.
• Studying spatial climate patterns by comparing the West Mediterranean and West-Central African precipitation stacks.

Strengths

• Data covers a 70,000-year time range, enabling analysis of long-term climate trends.
• Reconstructions are quantitative, providing mean annual precipitation values in mm/year.
• Methodology is explicitly stated as using the WA-PLS regression transfer function.
• Aggregates data from seven distinct fossil pollen records, likely improving regional signal representation.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is small at 51.3 KB, indicating limited scope or highly summarized data.
