<p> Monthly median and annual mean values of optical depth and
the ratio of diffuse to direct solar radiation for 1981-1983 were
calculated using integrated values of global and diffuse radiation
and calculations of precipitable water, under cloudless conditions.
Results indicate that El Chichon's volcanic dust cloud has affected
turbidity over southern Ontario. This is reflected in an increase
in optical depth and the ratio of diffuse to direct solar radiation. </p> / Thesis / Bachelor of Arts (BA)
