The ash and smoke cloud ejected by Mount Pinatubo in 1991 contained about twice as much matter as that thrown up by the El Chichn volcano (1982), making Pinatubo perhaps the largest eruption of the 20th century. Pinatubo's eruption in 1991 reportedly emitted more than 15 million tons of SO 2 into the stratosphere that mixed with water to form tiny sulfate aerosols that reflect solar radiation into space reducing global temperature [5]. Compared to today, the technology we had in the weather office was limited to teletype equipment and a Unix machine onboard the ship that received and processed (data from) NOAA Polar-orbiting satellites and ran a rudimentary plume model that wasn't designed to forecast volcanic ash movement. Huge quantities of particles from Pinatubo's tall ash cloud injected into the global wind system in the stratosphere.
