MISO: Southern Ocean Aerosol Chemistry Measurements from January–March 2024

MISO - Real-time aerosol chemistry measurements (ToF-ACSM) from the RV Investigator voyage IN2024_V01 presents the composition of non-refractory aerosols measured during a Southern Ocean research voyage. The voyage, titled 'Multidisciplinary Investigations of the Southern Ocean (MISO)', was conducted from 2 January to 5 March 2024, departing Hobart and returning to Fremantle. The dataset provides high-resolution, real-time measurements of nitrate, ammonium, sulfate, organics, chloride, and sea salt, contributed by the Australian Ocean Data Network.

Use Cases

• Modeling aerosol-cloud interactions based on high-resolution chemical speciation data.
• Analyzing ocean-atmosphere biogeochemical cycles based on measured aerosol species like nitrate and sulfate.
• Studying seasonal aerosol composition in the Southern Ocean based on the January to March 2024 time range.
• Investigating climate dynamics based on real-time measurements of aerosol chemistry.

Strengths

• Provides high-resolution, real-time measurements of aerosol chemical species.
• Covers a specific research voyage (IN2024_V01) from 2 January to 5 March 2024.
• Focuses on the critical Southern Ocean region for climate studies.

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 single voyage.
