Atmospheric Data from the RSV Nuyina Denman Marine Voyage, 2025

Voyage 3 of the RSV Nuyina collected detailed atmospheric measurements near the Denman Glacier in the 2024/2025 season. The dataset includes aerosol particle size distributions, cloud condensation nuclei counts, vertical thermodynamic profiles from radiosondes, and remote sensing of cloud and precipitation properties from instruments like a microwave radiometer and a micropulse lidar. Data were aggregated by the Australian Ocean Data Network and last updated in June 2026.

Use Cases

• Modeling aerosol-cloud interactions based on simultaneous aerosol particle and cloud property measurements.
• Analyzing vertical atmospheric structure based on temperature, pressure, humidity, and wind profiles from radiosondes.
• Studying precipitation microphysics based on reflectivity and Doppler spectra from a microrain radar.
• Retrieving atmospheric profiles based on brightness temperature data from a 35-channel microwave radiometer.

Strengths

• Data collection covers multiple atmospheric variables including aerosol microphysics, cloud properties, and precipitation.
• Instruments used are specified, such as Scanning Mobility Particle Sizer (SMPS) and Condensation Particle Counters (CPC) models 3776 and 3772.
• Remote sensing includes 35-channel brightness temperature measurements from a microwave radiometer.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Freshness should be verified as the last metadata update was 2026-06-04.
