Abstract	:	In this dissertation we explore multi-scale, convective transport through the Earth'splasma sheet using in situ observations and global terrestrial magnetospheric simulations.We statistically test the Lyon-Fedder-Mobarry (LFM) global magnetohydrodynamic (MHD)model with observations from the Geotail spacecraft at a variety of spatial and temporalscales within the plasma sheet. These comparisons, in addition to quantifying the LFMrange of validity, illuminate model shortcomings and highlight the additional physics nec-essary to resolve datalmodel discrepancies. First, we perform the first ever comprehensivevalidation of the LFM in the plasma sheet. We show that the LFM largely reproducesglobal, long-term average plasma sheet properties and variability, but we also identify andcharacterize its systematic deficiencies. We find that the LFM overestimates the averageplasma sheet velocity, and show that a portion of this overestimate is reflected in exces-.,..tested for theQ1 PC1 bus cardBoth these projects mere sofixare des elopment efforts tonards contributing to dlfferentaspects of Roboucs and lZ1echatronics projects m the Controls and Roboucs Group..
