Lidar observation of stratospheric aerosol increase after the El Chichon eruption: Nagoya, April to December 1982
The volcano El Chichon (Mexico) erupted violently over several days at the end of March and at the beginning of April 1982. After the eruptions a sudden increase of backscattered light from the stratospheric aerosol layer was detected by a lidar (0.6943μm) at Nagoya (35°N, 137°E) in mid-April 1982....
