Brief description

Data have been collected from muon detectors in cosmic ray observatories/laboratories at Macquarie Island, Wilkes, Casey and Mawson. Data have been collected from varied detectors and detecting systems, specific operational times and detector information are available on request. This dataset contains normalised counting rate records from the combined north/south pointing proportional counter telescopes P2 and P3 in low and high zenith angle modes, corrected for atmospheric pressure variation. No correction has been made for height or temperature of the 125mb level resulting in a significant seasonal variation but no diurnal variation at Antarctic latitudes. The telescope output consists of the sum of the 2-fold coincidence counting rates. Coincidence counts from individual counter pairs are summed into thirteen possible arrival zenith angles and two arrival directions (north or south). The low zenith data are hourly sums of coincidences from the seven lowest zenith angles of arrival (34 degrees -51 degrees) and the high zenith data are hourly sums of coincidences of the remaining six zenith angles of arrival (55 degrees -79 degrees).
