Antarctic observatories at Macquarie Island, Wilkes, Casey, and Mawson collected normalized muon counting rates. The dataset contains hourly sums of coincidence counts for thirteen zenith angles and two arrival directions, corrected for atmospheric pressure. Data were collected by the Australian Antarctic Data Centre using north/south pointing proportional counter telescopes.
Use Cases
- Analyze seasonal variation in muon flux using normalized hourly counting rates.
- Model atmospheric pressure effects on cosmic ray detection with pressure-corrected data.
- Study arrival direction anisotropy by comparing north and south pointing telescope data.
- Investigate zenith angle distribution using the thirteen angle bins of coincidence counts.
- Remove accidental coincidence rates using the documented resolving time difference method.
Strengths
- Data from four distinct Antarctic and sub-Antarctic observatory locations.
- Hourly temporal resolution for low and high zenith angle coincidence sums.
- Correction applied for atmospheric pressure variation to normalize rates.
Limitations
- No correction for height or temperature of the 125mb level introduces significant seasonal variation.
- Specific operational times and detector system details are not publicly documented and are available only on request.
- The sample size, row count, and exact time range are unknown.
