This record describes the set of recent vector magnetic observations available from Project MAGNET flights in the Australian region. It details the derivation from this of a set of 1-min (11 km) averaged values over ocean areas and 6-s (1.1 km) averaged values over land areas which is suitable for use in regional field modelling. Project MAGNET, an aeromagnetic survey of all accessible ocean areas of the world, was commenced by the U.S. Naval Oceanographic Office in 1953 and is still running. Its purpose is to maintain an up-to-dateset of high-altitude (6-10 kin) vector observations for use in geomagnetic field modelling and other geophysical studies. Data from Project MAGNET are made available free of charge through the National Oceanographic and Atmospheric Administration's National Geophysical Data Centre (NGDC) to institutions that contribute to the global pool of geomagnetic data. In addition to global surveying, Project MAGNET also involves special regional surveys. Such a survey was conducted over Australia in 1990 in conjunction with the AWAGSexperiment (Chamalaun and Barton, 1990).
