Molecular Composition of Cloud Water in Southern China from FT-ICR MS

A 2021 dataset of molecular composition data for cloud water collected in southern China, obtained by Electrospray Ionization Fourier Transform Ion Cyclotron Resonance Mass Spectrometry (ESI FT-ICR MS). The data was produced by Wei Sun of the Chinese Academy of Sciences for a study published in the journal Atmospheric Chemistry and Physics.

Use Cases

• Analyzing the molecular diversity of organic compounds in cloud water based on high-resolution mass spectrometry data.
• Investigating aqueous-phase chemical transformation pathways based on the molecular characteristics described.
• Modeling the role of cloud processing in atmospheric aerosol composition based on the identified molecular formulas.
• Comparing atmospheric organic matter composition across different geographic regions based on the southern China sampling location.

Strengths

• Data is associated with a peer-reviewed scientific article published in Atmospheric Chemistry and Physics.
• Molecular composition was obtained using high-resolution ESI FT-ICR MS, a technique capable of identifying thousands of unique molecular formulas.
• The dataset has a clear provenance from the Chinese Academy of Sciences.

Limitations

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