Sentinel-5P Sulphur Dioxide - SO2

Evaluate and visualize


Sulphur dioxide enters the Earth’s atmosphere through both natural and anthropogenic (human made) 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. Sentinel-5P/TROPOMI instrument samples the Earth’s surface with a revisit time of one day with a spatial resolution of 3.5 x 7 km which allows the resolution of fine details including the detection of smaller SO2 plumes. Measurements are in mol per square meter (mol/ m^2). Find more information here.
