A three-dimensional compressible resistive magnetohydrodynamic simulation code, with inclusion of the fully generalized Ohm's law, has been developed to study the nonlinear evolution of field line resonances in Earth's magnetosphere. A simple Cartesian box model of an inhomogeneous plasma with...

Significant populations of electrons with energies of tens of keV appear in the Earth's inner central plasma sheet during the substorm expansion phase. Increasing observational evidence indicates that these injections begin at a radially narrow but azimuthally extended transition between very...

Methane (CH4) is a greenhouse gas with an elevated global warming potential (GWP) equivalent to 28 times that of CO2. Also, production of enteric CH4 results in a 2 to 12% loss of the gross energy intake of cattle thus knowing the amount of CH4 released to the environment is important. The...

Magnetohydrodynamic, field line resonances in the Earth's magnetosphere can have very large velocity shears and field-aligned currents. Auroral radar measurements of high-latitude resonances indicate that the velocities associated with the resonances in the E and F regions am often substantially...
