The major eruption of Mt Pinatubo on June 15, 1991 ejected 20 megatons of sulfur dioxide into the stratosphere at altitudes of 20-30 km. The sulfur dioxide converts to sulfuric acid vapor in 30-40 days, the vapor thus formed nucleates, condensing with water to form sulfuric acid aerosol. The resident time of this aerosol is several years and significantly increases the planetary albedo. A new method is presented for the detection of sulfuric acid aerosol utilizing observations made by polar orbiting satellites of brightness temperature differences at two thermal wavelengths. Time series of this difference shows an increase of 2.4 K after the eruption, a value in agreement with radiative transfer calculations based on in-situ observations of the sulfuric acid aerosol. This new method can be used to map globally the distribution of the sulfuric acid aerosol and obtain an estimate for the mass loading, necessary information for climate models attempting to study the impact of the Pinatubo eruption.
