Sulfur Dioxide (SO2) Concentration

This dataset provides near real-time high-resolution imagery of atmospheric sulfur dioxide (SO2) concentrations. Sulphur dioxide (SO2) enters the Earth’s atmosphere through both natural and anthropogenic processes. It plays a role in chemistry on a local and global scale and its impact ranges from short-term pollution to effects on climate. Only about 30% of the emitted SO2 comes from natural sources; the majority is of anthropogenic origin. SO2 emissions adversely affect human health and air quality. Geospatially derived sulfur dioxide (SO2) concentration is a measure of the amount of sulfur dioxide, a toxic gas, in the atmosphere at a given location. This concentration is typically determined using satellite-based sensors, which can detect the presence of SO2 in the atmosphere. Sulfur dioxide is a harmful air pollutant that can have negative impacts on human health and the environment. The concentration of SO2 in the atmosphere can be represented as a map or spatial dataset using geographic information systems (GIS) technology, and can be used to monitor and manage air pollution.
