Volcanic dust has been used in the past as a tracer or' atmospheric motions. The volcanic dust resulting from the eruption of Mt. Agung, Bali (8° S, 115°E) w March 1963 produced some spectacular effects in the southern hemisphere as seen from the radiation observations made at Aspendale (38° S, 145°E). The diffuse radiation mesurements made at Poona, however, do not show such effects to any appreciable extent. It is, therefore, concluded that the transport from the southern to the northern hemisphere of stratospheric dust is of a much smaller magnitude than the transport within the southern hemisphere itself.
