<span class="contentpasted0"><span lang="EN" style="color:#222222">Plasma instabilities in the high, middle, and low latitude ionosphere play a key role in the development and evolution of structures in the Geospace environment, including processes in both
the E and F regions. They often are associated with irregularities which can be experimentally observed using radar and radio techniques, as well as in-situ observations. Linear and non-linear theory is often used to predict instability thresholds, amplitudes,
and velocities. Simulations have recently been quite successful in the detailed study of irregularity micro-structure, time evolution, and k-space behavior. This session encourages discussion of new developments in the theoretical, simulation, and experimental
observations relevant to the study and understanding of ionospheric plasma instabilities. The effects of ionospheric instabilities on other Geospace phenomena will also be of interest. This includes coupling to the magnetosphere and impacts of the lower atmosphere
on instability growth and development. </span></span><span style="color:#222222"> </span><span style="color:black"><o:p></o:p></span></p>
