Sulfur concentration data was collected from tagged air masses during the 1992 ASTEX/MAGE multinational field experiment in the eastern North Atlantic. Measurements were derived from ion chromatograms of ship-collected samples stored in liquid nitrogen. The dataset was produced by the LARC_ASDC organization to study cloud-chemistry interactions and air/sea fluxes.
Use Cases
- Analyze sulfur concentration variability to evaluate the impact of natural versus anthropogenic sulfur on marine aerosol chemistry.
- Correlate trace-gas and aerosol flux estimates from ship-based measurements with meteorological data to test Lagrangian airmass tracking strategies.
- Use calculated concentrations from ion chromatogram peak height ratios to study the role of aerosols in stratocumulus cloud formation and dissipation.
Strengths
- Data originates from a coordinated multinational field experiment combining ship, balloon, and aircraft observations.
- Concentration uncertainties were estimated using a propagation of errors calculation considering standard concentration and signal-to-noise error.
Limitations
- Dataset is temporally limited to a single intensive field-observation period in June 1992.
- Sample size and specific row/column counts are unknown, limiting reproducibility assessments.
- Geographic coverage is restricted to the eastern North Atlantic Ocean during the experiment.
