MISO: Real-time Aerosol Chemistry Measurements from the Southern Ocean Voyage IN2024_V01

High-resolution, real-time measurements of non-refractory aerosol composition were captured during a 2024 Southern Ocean research voyage. The data includes nitrate, ammonium, sulfate, organics, chloride, and sea salt concentrations, measured by a Time-of-Flight Aerosol Chemical Speciation Monitor (ToF-ACSM). This dataset from the Australian Ocean Data Network supports research into ocean-atmosphere interactions and climate dynamics.

Use Cases

• Modeling aerosol-cloud interactions based on high-resolution, real-time aerosol species measurements.
• Analyzing seasonal or spatial trends in Southern Ocean aerosol composition based on voyage-track data.
• Studying the role of sea salt aerosols in climate dynamics based on chloride and sea salt concentration data.
• Investigating links between biological activity and aerosol chemistry based on organic and sulfate measurements.

Strengths

• Data provides high-resolution, real-time measurements of aerosol species.
• Measurements cover a specific two-month voyage from 2 January to 5 March 2024.
• Dataset focuses on the climatically critical Southern Ocean region.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic and temporal bias inherent to a single research voyage.
