During September and December, 1965, trials were held at Camp Shilo, Manitoba, to study the effects of meteorological conditions on sound transmission paths, to determine the meteorological requirements for sound ranging, and to study methods of applying meteorological corrections to locations made by sound randing. Results from the Phase A trials (September) indicate that the Goodwin correction method results in a significant improvement in location accuracy over that obtained using the weighted-wind correction technique. The results also indicate that meteorological data is required to a height of 2500 metres for source-to-microphone distance of 40 kilometres.
