RV Investigator Ultrafine Aerosol Volatility and Hygroscopicity (VH-TDMA) - Selected Voyag

2016 onwards measurements of ultrafine aerosol volatility and hygroscopicity collected aboard the RV Investigator. The dataset was generated using a purpose-built VH-TDMA instrument constructed at QUT, which conditions particles using a thermodenuder and humidifier. Data collection is managed by the Australian Ocean Data Network, with the latest metadata update in June 2026.

Use Cases

• Modeling aerosol volatility based on thermodenuder temperature settings mentioned in the description
• Analyzing particle hygroscopic growth based on controlled relative humidity cycles described
• Studying ambient marine aerosol size distributions from selected particle diameter measurements
• Calibrating aerosol instrumentation using the described size calibration and deliquescence relative humidity scans

Strengths

• Instrumentation details are specified, including the use of three electrostatic classifiers and two condensation particle counters.
• The description provides specific operational parameters, such as common particle diameters (40, 100, 150 nm) and a primary thermodenuder temperature of 250 °C.
• The data collection platform, the RV Investigator, suggests a controlled marine sampling environment.

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 temporal and geographic bias inherent to the specific voyages of the RV Investigator.
