Cosmic Ray Underground Muon Data from Mawson, Antarctica provides hourly muon count rates from two directional telescopes. The Australian Antarctic Data Centre manages data collected by proportional counter telescopes installed in 1982, with some records dating back to 1972 from earlier Geiger counter systems. Data includes raw counts and pressure-corrected rates from north and southwest viewing directions.
Use Cases
- Analyze muon flux time series from the north-pointing telescopes (P6, P7) for correlation with solar activity cycles.
- Compare pressure-corrected count rates between the north (Zenith 24°, Azimuth 330°) and southwest (Zenith 40°, Azimuth 205°) viewing directions to study anisotropy.
- Model atmospheric pressure effects on underground muon detection using the provided corrected and uncorrected data streams.
- Investigate long-term trends in cosmic ray intensity using multi-decade records from proportional and Geiger counter telescopes.
Strengths
- Data spans multiple decades, with records from detectors installed in 1972 and 1982.
- Includes measurements from two distinct viewing directions (north and southwest) enabling directional analysis.
- Provides both raw muon counts and data corrected for atmospheric pressure variations.
Limitations
- Exact row count, temporal coverage, and data completeness are unspecified.
- Dataset description lacks explicit column definitions and sample data for verification.
Provenance
- Source
- Australian Antarctic Data Centre (AU_AADC) via NASA EarthData.
- Collection Method
- Collected by underground proportional counter and Geiger counter telescopes using 2-fold coincidence counting, with accidental rates removed via a resolving time difference method.
- Time Range
- Records begin in 1972; proportional counter data from 1982 onward.
- Freshness
- null
- Geography
- Mawson station, Antarctica, from an underground vault at 11 meters water equivalent depth.
