In addition, the level of ionization of the atmosphere has been proposed as an important mechanism that can modulate the low cloud cover formation (Tinsley, 2008; Kirkby, 2007; Svensmark et al., 2009). (landscheidt.info)
Solar activity usually tends to increase the rate of ionization in the atmosphere and thus the density of free electrons in the ionosphere or to move electrons to the polar caps. (sciencedaily.com)
Large changes in atmospheric ionization induced by sporadic SEP events may potentially also affect radio wave propagation in the Venusian atmosphere. (swsc-journal.org)
