Winter Fog Aerosol Measurements in Hong Kong with Single-Particle Mass Spectrometry

56.7% of particles analyzed were black carbon-related carbonaceous particles with substantial sulfate amounts. This dataset likely contains observations from three winter fog events in Hong Kong, analyzed using single-particle aerosol mass spectrometry (SPAMS) and a Monitor for AeRosols and GAses in ambient air (MARGA). The study was authored by Yang Zhou and is available via Open Access.

Use Cases

• Modeling sulfate formation pathways based on observations of hydroxymethanesulfonate (HMS) and iron mixing states.
• Analyzing the impact of aerosol acidity on metal dissolution and sulfur oxidation based on reported pH correlations.
• Studying fog scavenging effects on aerosol composition based on reported sulfate mass concentration changes.
• Investigating the role of the Fenton reaction in atmospheric chemistry based on the observed mixing of HMS with iron.

Strengths

• Includes specific quantitative findings, such as HMS accounting for up to 12% of particles by number fraction.
• Reports detailed correlations, such as the negative overall correlation (r = -0.51) between pH and HMS particles.
• Analysis is based on single-particle measurements, which likely provides high-resolution compositional data.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
