Sulphur Dioxide

DESCRIPTION

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. SO2 has an effect on climate through radiative forcing, via the formation of sulphate aerosols. Volcanic SO2 emissions may also pose a threat to aviation, along with volcanic ash. The S5P sensor TROPOMI samples the Earth’s surface with a revisit time of one day and with an unprecedented spatial resolution of 7x7 km. This allows the resolution of fine details and S5P will arguably be a valuable tool to better study anthropogenic SO2 emissions but also volcanic emissions, from degassing to eruptive processes.
