Abstract: Two monitors were built to determine the variation in cosmic-ray flux with altitude and geomagnetic latitude in the Southern Hemisphere (Australia – New Zealand – Antarctica). The portable monitors follow the IGY/NM-64 design and are equipped with 3He detector tubes. This report presents a full description of monitor design, operation, and calibration, and includes the results of field measurements carried out between 1998 and 2001. It thus provides the raw data from which cosmogenic nuclide production rates for the Southern Hemisphere can be calculated, and from which scaling factors used in surface exposure dating can be independently validated.
