Paper Abstract

Continental Argentina and Chile are extended on a very dangerous geographic situation in relation with the ozone layer depletion. Global reduction in total ozone can be related in part with the Antarctic's ozone hole and its dynamics of dilution; this phenomena is not well studied yet. To follow this process, a network of 16 simple and portable ozone meters has been developed. The instruments, installed from Arica (18 S) to Rio Grande (54 S), work by measuring the direct solar intensity at 300 nm and 313 nm. The ratio of these two measurements was related directly with ozone contents. Measurements during 1993 and 1994 have shown that when the ozone hole reached South America, a correlated reduction in the total ozone content can be observed in latitudes as low as 35 S. The origin of the ozone depletion detected over Argentina and Chile is discussed in relation with solar flares and circulatory dynamics.
