FIRE ASTEX MAGE: Marine Cloud Chemistry and Sulfur Data from the Eastern North Atlantic

The Eastern North Atlantic Ocean was the site of the 1992 ASTEX/MAGE field experiment. This dataset contains atmospheric chemistry measurements, focusing on sulfur species and aerosols, collected from ship-based sampling during the multinational campaign. Data were derived from ion chromatograms of samples stored in liquid nitrogen, with concentrations calculated from standard peak height ratios.

Use Cases

• Modeling the impact of natural and anthropogenic sulfur on marine aerosol chemistry based on the described trace-gas measurements.
• Studying chemical and meteorological evolution in a tagged airmass using the described Lagrangian strategy involving ships and aircraft.
• Evaluating the influence of aerosols on stratocumulus cloud formation and dissipation as referenced in the experiment goals.
• Developing techniques for estimating trace-gas and aerosol fluxes across the air/sea interface as a primary goal of the MAGE experiment.

Strengths

• Data originates from a coordinated multinational field experiment combining satellite, airborne, and surface observations.
• Concentration calculations and uncertainty estimates are described, involving standard peak height ratios and error propagation.
• Platform tags indicate specific Earth Science domains: Atmospheric Chemistry and Aerosols.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
• Data files include legacy formats (BIN, TAR, ISO) that may require specific tools to access.
