A constellation of satellites, including the Chinese FengYun-3 (FY-3F and FY-3E) and the European Sentinel-5P quantified the sulfur dioxide (SO2) pollutant released from refinery fires on March 7.  The study confirmed that SO2 concentrations rose from a regional mean of 0.8 DU to 2.0 DU during the event, with total emissions estimated at 2.98×104 tons.
