Estimates of sulfur and chlorine yield to the atmosphere from volcanic eruptions and potential climatic effects.
Date of Original Version
Reports analytical methods based on electron microprobe analysis of volcanic tephra which allow estimation of minimum masses of sulfur and chlorine released to the atmosphere by volcanic eruptions. Declines in mean northern hemisphere surface temperatures associated with several recent eruptions (Laki 1873, Tambora 1815, Krakatau 1883, Agung 1963, Mount St. Helens 1980) are positively correlated with our estimates of the minimum mass of sulfur released to the atmosphere, reinforcing the idea that sulfate aerosols have a greater climatic impact than volcanic 'dust'.-from Authors
