Measurement of ozone, UVB radiation is a concern over Latin America



A clear recognition of the unique role that Latin America plays in the global environment was one of several major themes to emerge at a recent workshop on distributions of ozone and UVB radiation over Latin America. The region covers a very broad latitude range and has a major influence on the atmospheric circulation of the southern hemisphere. The Andes Mountains, which cover a latitudinal range of more than 60° and are from 2 o 7 km in altitude, are unique not o nly because they force gravity waves, but also because of the opportunity they provide for satellite instruments to differentiate between columns of air over high mountains and nearby sea level. Appreciable emissions of trace gases and particles from both natural and human activity in Latin America have important effects on both regional and global scales.
