A time series of aerosol concentration profiles for the lower stratosphere was obtained at 34° S. (Mildura, Australia) during the 12 months after the eruption of Fuego volcano in Guatemala in October 1974. A persistent thin aerosol‐rich layer was found at or near 17 km; it existed from late 1974 and was replenished in the southern winter of 1975. The available evidence indicates that the initial layer was probably not due to the Fuego eruption.
