Stratosphere Ozone is the layer of life-protecting O3 from ultraviolet (UV) (Krizan, Miksovsky et al. 2011). O3 in this layer is gradually being destroyed, largely due to the release of chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), halons, methyl bromide, carbon tetrachloride, and methyl chloroform. Scientists recently discovered chemical O3 destruction over the Arctic in early 2011. It was the first time in the observational record, compared to in the Antarctic O3 hole (Manney, Santee et al. 2011). O3 depletion can cause increased amounts of UV radiation to reach the Earth which can lead to more cases of skin cancer, cataracts, and impaired immune systems. So2 is an invisible gas with a pungent, irritating smell that causes air pollution and acid rain by reacting with rain water to form sulfurous acid. About 99% of So2 in the air comes from human sources by the oxidation of the gaseous and the aqueous phase of long-lived So2 from combustion processes and the injection of volcanic emission. In addition, industrial activities can be important sources of So2 but not the main, source of So2 in air.
Recently, there has been an increased interest in O3 and So2 due to the ill-defined impacts of O3 and So2 radiative forcing and climate change. One criticism of much of the literature on these parameters is that the parameters have never been determined in UV by using Brewer#121 software. This study aims to explore O3 and So2 in tropical regions, resulting in an improved understanding of O3 and So2 climatology.
