Measured vertical profiles of temperature and wind and used to model infrasound propagation over a representative high savanna habitat typically occupied by the African elephant, Loxodonta Africana, to predict calling distance and area as a function of the meteorological variables. The profiles were measured up to 300 m above the surface by tethered balloon-borne instruments in Etosha National Park, Namibia, during the late dry season.
