A Southern Hemisphere Imaging Riometer Experiment maps 38.2 MHz cosmic noise and particle precipitation across a 7 x 7 beam grid, each beam covering 12.8 degrees. The project is a joint effort of the Australian Antarctic Division, University of Maryland, and the University of Newcastle. These data are part of the ongoing ASAC project 877 and are held on servers at the Australian Antarctic Division.
Use Cases
- Analyze auroral particle precipitation patterns based on cosmic noise intensity measurements
- Study ionospheric disturbances in the Southern Hemisphere based on the 38.2 MHz radio signal data
- Map spatial variations in cosmic noise absorption across a ~200 x 200 km area at 90 km altitude
Strengths
- Data is collected from a 7 x 7 beam grid, providing spatial resolution
- Focuses on a specific 38.2 MHz frequency for cosmic noise measurement
- Project is a joint effort of three institutions: Australian Antarctic Division, University of Maryland, and University of Newcastle
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
