Adding to this theory is fairly strong evidence that a decrease in UV light will result in a more meridional atmospheric circulation (which should cause more clouds, precipitation and snow cover for the N.H.), due to changes in
ozone distribution in a vertical / horizontal sense which would cause the temperature contrast between the polar areas of the stratosphere and lower latitude areas of the stratosphere to lesson, during prolonged solar minimum periods.
A study
of ozone distribution after such events may be particularly important for validating photochemical - diffusion models.
Fourth, volcanic aerosols provide surfaces for heterogeneous chemistry affecting global
stratospheric ozone distributions (Chipperfi eld et al., 2003) and perturbing other trace gases for a considerable period following an eruption.
For starters, the orbiter beamed back incredibly detailed stereo photos of the surface, measured
the ozone distribution in the planet's atmosphere, and confirmed the presence of water ice at the south pole.
An increase in the concentrations of LLGHGs, especially CO2, cools the stratosphere, allowing the possibility of more PSCs, and alters
the ozone distribution (Rosenlof et al., 2001; Rosenfield et al., 2002; Randel et al., 2004, 2006; Fueglistaler and Haynes, 2005).
