Using a new satellite-based method, scientists at NASA, ECCC, and two universities have located 39 unreported and major human-made sources of toxic sulfur dioxide emissions. A known health hazard and contributor to acid rain, sulfur dioxide (SO2) is one of six air pollutants regulated by the US EPA. Current, sulfur dioxide monitoring activities include the use of emission inventories that are derived from ground-based measurements and factors, such as fuel usage.
