Infrasound and Satellite Observations of Popocatépetl Volcano Eruptions

15 eruptive events from Popocatépetl volcano are documented with infrasound array detections and GOES-16 satellite ash pixel counts between May and September 2023. Santiago Piñón Juárez and colleagues compiled this dataset to support research on eruption source parameter retrieval. The collection includes CSV files with time-series parameters, miniSEED seismic recordings, and geospatial TIF imagery.

Use Cases

• Correlate `ash` and `cloud` pixel counts from satellite data with infrasound `pressure` and `detections` to validate eruption timelines.
• Model volcanic source parameters by analyzing relationships between infrasound `backazimuth`, `coherence`, and derived `qi` (volumetric flux).
• Train models to classify eruptive events using features like `ip` (infrasonic parameter), `fq` (dominant frequency), and `mp` (maximum pressure).
• Study atmospheric propagation effects on infrasound by integrating `backazimuth` data with the `atm_profile.csv` atmospheric profile.

Strengths

• Multi-modal data fusion from two infrasound arrays (PCS, POP) and the GOES-16 ABI satellite sensor.
• Covers a 5-month observational period (May–September 2023) capturing 15 distinct eruptive events.
• Includes raw waveform data in miniSEED format alongside processed tabular parameters for reproducibility.

Limitations

• Limited temporal scope to 5 months in 2023, not suitable for long-term volcanic trend analysis.
• Spatial coverage is restricted to a 20 km region of interest around Popocatépetl volcano.
• Sample size of eruptive events is small (15 events), which may limit statistical model training.
