This is a $427,105.72 grant awarded to The Johns Hopkins University by the National Aeronautics and Space Administration (NASA) for a research project to study the effects of dayside ionospheric conductance on the structure and dynamics of the magnetotail. The primary goal is to identify and evaluate the active role of the dayside ionospheric conductance in the solar wind-magnetosphere-ionosphere coupling. The research will use satellite data analysis and global magnetohydrodynamic modeling to address how the magnetotail configuration and plasma sheet convection differ for different ionospheric conductances. This grant is part of NASA's Heliophysics research program and is relevant to the science goals of the Magnetospheric Multiscale (MMS) mission. The contract has no set-aside designation and was awarded on April 1, 2016 with a final completion date of September 10, 2021.
