Real-time aerosol composition data, including nitrate, ammonium, sulfate, organics, chloride, and sea salt, measured during the RV Investigator voyage IN2024_V01 from 2 January to 5 March 2024. The voyage, titled 'Multidisciplinary Investigations of the Southern Ocean (MISO)', was conducted in the Southern Ocean, departing Hobart and returning to Fremantle. The dataset provides high-resolution measurements for studying aerosol roles in climate dynamics and biogeochemical cycles.
Use Cases
- Model aerosol-cloud interactions based on real-time aerosol species composition
- Analyze ocean-atmosphere chemical exchanges based on sea salt and chloride measurements
- Study biogeochemical cycles in the Southern Ocean based on nitrate and sulfate data
- Investigate climate dynamics based on high-resolution aerosol composition time-series
Strengths
- High-resolution, real-time measurements of aerosol species
- Data collected during a dedicated 2-month multidisciplinary voyage in the Southern Ocean
- Includes specific aerosol components: nitrate, ammonium, sulfate, organics, chloride, and sea salt
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/temporal bias inherent to the specific voyage
