A NASA research team published in the Journal of Geophysical Research its findings on urban-like pollution over the tropical South Atlantic Ocean. The team used data gathered from an experiment called the Transport and Chemistry near the Equator of the Atlantic (TRACE-A), conducted with the Brazilian Space Agency and scientists from South Africa. The scientists suspected that the high concentrations of ozone, like those found in densely populated urban areas, resulted from seasonal burnings in South America and Africa. According to the NASA researchers, the presence of pollution over the tropical ocean confirmed that humans had extended their negative impact on "traditionally pristine air" far beyond reaches directly above land. According to one researcher, the results of TRACE-A greatly improved the scientific community's understanding of the atmospheric chemistry of the Southern Hemisphere.
