IMPACT OF AEROSOLS FROM THE ERUPTION OF EL CHICHÓN ON BEAM RADIATION IN THE PACIFIC NORTHWEST The eruptions of the Mexican volcano El

The eruptions of the Mexican volcano El Chichón over the period of March 28 to April 4, 1982 ejected an amount of ash comparable to that spewed forth from Mount St. Helens in May of 1980. While the volume of ash ejected by the two eruptions was comparable, the stratospheric cloud created by the eruption of El Chichón was over 140 times denser. Utilizing the scattering of laser light by the material in the atmosphere, scientists at the National Aeronautics and Space Administration's Langley Research Center determined that the dense stratospheric cloud was about 2.5 kilometers wide and was situated at an altitude of 25 kilometers [1]. The effect of this dense cloud upon the atmosphere and climate in the Northern Hemisphere is the largest since the eruption of the Indonesian volcano Krakatau in 1883.
