Description
Our understanding of the Sun-Earth connection at high latitudes originates largely from observations made in the Arctic, and traditionally global models are using input only from the northern hemisphere, implicitly assuming hemispherical symmetry.
There are now several well-known asymmetries between the two polar atmospheres and ionospheres caused by, among other things, the different landmass distribution and hence atmospheric circulation patterns and temperatures, and the different offsets between the geographic and magnetic poles, resulting in very different geomagnetic regions being exposed to similar solar input at any given time of day and season. How large these effects are in the upper atmosphere and ionosphere region and their coupling to the magnetosphere and the solar wind are not very well known. Only by long semi-continuous observations of the variability in the high latitude southern hemisphere can one potentially gain new insight into these questions.
Only now, with the advent of easily reproducible AMISR technology which is designed for unmanned remote operation in extreme locations, does the possibility exist to make such an observing program in Antarctica a reality.
In this workshop we would like to invite speakers and open discussion on topics related to interhemispheric studies, potential biases in global models due to the strong northern hemisphere biased input, and general aeronomy unique to the high south.
