The Atlantic Stratocumulus Transition Experiment (ASTEX) and Marine Aerosol Gas Exchange (MAGE) experiment collected meteorological and atmospheric chemistry data in the eastern North Atlantic Ocean during June 1992. This dataset from NASA's LARC ASDC organization supports research on marine cloud formation, dissipation, and air-sea interaction processes. It combines coordinated satellite, airborne, and surface observations from a multinational field campaign.
Use Cases
- Study cloud dissipation factors by analyzing time-series of meteorological variables like wind speed, temperature, and humidity from ship and aircraft instruments.
- Evaluate aerosol impact on stratocumulus clouds by correlating atmospheric chemistry measurements with cloud property observations.
- Test Lagrangian modeling strategies by tracking the evolution of trace-gas concentrations and meteorological conditions within a tagged airmass.
- Investigate air-sea flux estimates by comparing traditional and experimental measurements of trace-gas and aerosol exchanges.
Strengths
- Data collected during a dedicated 28-day intensive field observation period in June 1992.
- Multinational, multi-agency experiment combining satellite, airborne, balloon, and ship-based observations for coordinated analysis.
Limitations
- Dataset is temporally limited to a single month of observations from 1992, lacking long-term temporal coverage.
- Specific data volume, row count, column names, and file formats are not documented in the provided description.
