CEDAR email: Announcement for EGU session on asymmetries effects in geospace and planetary environments

[Paul Tenfjord]

Dear colleagues,

We are convening a session PS4.8/ST2.10entitled “***Asymmetries in 
geospace and planetary environments*” at EGU 2018 conference to be 
held on 8- 13April in Vienna, Austria.

We invite researchers to submit abstracts to this session. Please find 
more information here:

Session details:

The Sun-Earth interaction leads to a variety of asymmetric effects in 
geospace. In the ionosphere these appear, for example, as dawn-dusk 
asymmetries and inter-hemispheric asymmetries and in the magnetosphere 
they can be observed, for example,  as warping of the plasma sheet, 
asymmetric loading of flux in the lobes, and in ion outflow.

Known causes  of asymmetries include the orientation of the 
interplanetary magnetic field, the tilt angle of the Earth, solar 
irradiation, variations in magnetic field strength, and disparities in 
neutral wind forcing from below.  As the state of geospace is a result 
of all these various factors, the most common state of geospace is 
indeed asymmetric.

This section calls for a papers exploring geospace in order to make 
progress in our understanding of the physical processes responsible for 
creating the asymmetric geospace. We welcome studies using observations, 
statistical techniques, as well as MHD modeling, simulations and 
theoretical considerations.
Studies of dynamics and asymmetries from other planets are also welcome.

Best regards, Paul, Jenny, and Rumi
