Data from the 1992 ASTEX/MAGE field experiment in the eastern North Atlantic Ocean, focused on cloud-chemistry interactions and air-sea fluxes. The dataset contains sulfur and aerosol concentration measurements derived from ship-based ion chromatograms. It was collected by the LARC_ASDC organization as part of a multinational atmospheric research effort.
Use Cases
- Analyze sulfur concentration time-series to study natural versus anthropogenic sulfur impacts on marine aerosol chemistry.
- Correlate aerosol concentration measurements with meteorological data to evaluate aerosol impacts on stratocumulus cloud formation and dissipation.
- Use trace-gas concentration data to develop and test models for estimating air/sea interface fluxes.
- Apply Lagrangian strategy data from ships, balloons, and aircraft to study chemical and meteorological evolution in a tagged airmass.
Strengths
- Data collected during a coordinated, month-long intensive field observation period from June 1-28, 1992.
- Multinational, multi-agency experiment combining satellite, airborne, and surface observations with modeling studies.
- Measurements derived from direct ion chromatogram analysis with standards for concentration calculation.
Limitations
- Dataset size, row count, and specific column schema are unknown.
- Temporally limited to a single field campaign from 1992, lacking contemporary measurements.
- Geographic scope is restricted to the eastern North Atlantic Ocean during the experiment period.
