AARDDVARK/WWLLN sensor data from Arrival Heights, Antarctica, measures magnetic fields in the 500 Hz-50 kHz range to probe the upper atmosphere. The narrowband dataset captures amplitude and phase of distant VLF communication transmitters with 0.2-second time resolution. This 10th station in the AARDDVARK network, led by the University of Otago and British Antarctic Survey, aims to understand energy coupling between Earth's atmosphere, Sun, and Space.
Use Cases
- Modeling subionospheric radio wave propagation based on amplitude and phase measurements at specific transmitter frequencies.
- Analyzing ionospheric disturbances and energy coupling based on changes in ionization levels between 30-85 km altitude.
- Monitoring long-range VLF communication transmitter signals across northern and southern hemispheres.
- Studying space weather impacts on the upper atmosphere using the atmosphere as an energetic particle detector.
Strengths
- Data has a high temporal resolution of 0.2 seconds.
- Sensor is part of a wider international network (AARDDVARK) with 10 stations.
- Measurements target a specific, scientifically relevant altitude range (~30-85 km).
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.
