Volcán de Colima 2013 Activity: SO2 Emissions and Ash Composition

1.5 GB of data from the 2013 active phase of Volcán de Colima, México, collected under NERC grant NE/L000741/1. The dataset comprises SO2 emission measurements from SO2 camera and DOAS instruments, alongside Scanning Electron Microscope images and microprobe data of ash and rock samples. These data were used in the 2015 Earth and Planetary Science Letters paper 'Rapid and slow: Varying ascent rates as a mechanism for Vulcanian explosions'.

Use Cases

• Modeling SO2 flux and emission patterns based on the time-series SO2 camera and DOAS data.
• Analyzing ash particle morphology and mineral composition based on the Scanning Electron Microscope images.
• Correlating gas emission data with physical rock and ash properties to study eruption mechanisms.
• Validating volcanic plume dispersion models using the ground-based SO2 measurements.

Strengths

• Dataset size is explicitly stated as 1.5 GB, indicating substantial raw data.
• Data is directly linked to a peer-reviewed publication, providing context and validation.
• Combines multiple data types (gas emissions and physical sample analysis) for a single volcanic event.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is specific to a single volcanic event in 2013, limiting temporal generalizability.
