A significant enhancement of the stratospheric aerosol and condensation nuclei levels was observed at Laramie, Wyoming beginning in May 1981, following the eruption of the volcano Alaid (50.8°N, 155.5°E) on April 28. Observations to mid‐July suggest that in terms of effects on the stratosphere, the eruption was similar to that of Mt. St. Helens in May 1980.
Hofmann et al. (1981) studied this question.
