High ozone (O3) concentration near the surface can provoke health issues which affects the pulmonary system. Thanks to the ozone presence that exists above the tropopause we are protected from incoming solar radiation. Due to the industries and vehicles, the presence of ozone is heavier in big cities. Places like the South Atlantic have a highest ozone level, which is mainly produced by biomass burning and lightning. The goal of this research is to detect whether if the ozone is coming from South America or Central Africa, and to determine its altitude in the atmosphere. Using the HYSPLIT model can determine if the ozone is coming horizontally or vertically, and its principal source. Using weather satellite image we can detect rain, thunderstorm, and fire over South America and Central Africa. During the months of August and September the ozone detected in the lower troposphere came from the South Atlantic. Meanwhile, the ozone in the middle troposphere was located in both the South Atlantic and Central Africa. The lower ozone peak values are representative of the South Atlantic because the air in this region has a low concentration of ozone which is good. High ozone concentrations detected during August and September came from Central Africa principally. Ozone found in the upper troposphere is related with lightning because its peak was detected at the same altitude where lightning occurs. This ozone peak came from Central Africa and South Atlantic principally.
