Historical Sea-Level Pressure Comparison for Italian Stations on September 15, 1882

September 15, 1882, provides a comparison of sea-level pressure (SLP) values from RCMO bulletins at selected Italian stations against data from the 20th Century Reanalysis (20CR). The dataset was created by Alessandro Ceppi and published under a CC BY 4.0 license. It is a small, focused dataset stored in an XLS file with a size of 9.5 KB.

Use Cases

• Compare SLP values from RCMO bulletins with 20CR reanalysis data for synoptic reconstruction of the September 15, 1882 event.
• Analyze the agreement between station-reported SLP and 20CR model outputs to assess historical data quality for selected Italian stations.
• Use the digitized SLP comparison to validate or calibrate other historical climate reconstructions for the late 19th century.

Strengths

• Focuses on a specific, well-defined historical meteorological event on September 15, 1882.
• Provides a direct comparison between two distinct data sources: RCMO station bulletins and the 20CR reanalysis.
• Published under a permissive CC BY 4.0 license, facilitating reuse and sharing.

Limitations

• Extremely limited temporal scope, covering only a single day (September 15, 1882).
• Small dataset size (9.5 KB) indicates very limited sample size, restricting statistical analysis.
• Unknown row and column structure limits understanding of the dataset's granularity and completeness.
