SM14B:
Multiscale Structure and Dynamics of Earth's Dayside Magnetopause:  Results from the First MMS Dayside Season II

Submit an Abstract to this Session Please know the abstract submission deadline has passed. There are no exceptions to this deadline and no new abstracts can be submitted.
You can still search the program to see your colleague�s abstract submissions as well as the sessions submitted for the 2016 Fall Meeting. The final program will be released in early October.


Session ID#: 17833

Session Description:
NASA's Magnetospheric Multiscale (MMS) mission completed its first dayside season on March 8, 2016.  With a spacecraft separation as small as 10 km, MMS now probes the sub ion-scale structure of Earth's dayside magnetopause, observing the plasma and fields at comparable temporal resolutions for the first time.  Comparison of these observations with simulations has provided many new insights into the structure of the magnetopause boundary layer, including:  the structure of the electron and ion diffusion regions in asymmetric reconnection, the ion-scale structure of reconnection exhausts, the role of secondary islands in the reconnection process, the nature of turbulent fluctuations in the magnetosheath and low latitude boundary layers, the kinetic structure of Flux Transfer Events (FTEs), and the large scale topology of the dayside magnetopause.  We solicit abstracts investigating these and related topics using observations, theory and modeling, and laboratory experiments, with emphasis on relevance to the interpretation of MMS data.
