The platforms support fluxgate and induction magnetometers, dual frequency GPS receivers, and a high-frequency radio experiment to investigate high latitude space weather phenomena. Recent research has focused on magnetohydrodynamic wave events initiated by solar wind pressure pulses and seasonal interhemispheric differences in conductivity.Exploring the upper atmosphere in the long polar nightA sounding rocket program is underway to explore the upper atmosphere of the Earth’s polar night. This region is difficult to access and is relatively unobserved. We are particularly interested in the concentration of aurora-produced nitric oxide—which is a catalytic destroyer of ozone. The long polar winter nights are expected to contain large levels of nitric oxide, but with few observations, this is not well understood.  To unlock mysteries of the geospace environment, ECE researchers send experiments up on sounding rockets and develop payloads for satellites.Aeronomy of iceECE researchers are engaged in further studies of middle atmosphere gravity waves in NASA’s Aeronomy of Ice (AIM) mission. New algorithms to determine stratospheric gravity wave morphology will be applied to more than 10 years of AIM observations to form a unique dataset for studying the coupling of the Earth’s upper and lower atmosphere.Impacts of space-weather events on the ionosphereECE researchers will be conducting atmospheric gravity wave studies via in-situ measurements of wave perturbations in the ionosphere and remote sensing of the middle atmosphere. These measurements can then be correlated with weather maps of the lower atmosphere, allowing for atmospheric coupling studies over a wide altitude range.Radiative impacts of pollutantsECE researchers are developing new instrumentation to observe the radiative impacts of pollutants. The new instruments are compact, robust, and suitable for implementation on constellations of satellites.Mapping geospace phenomenaThe Virginia Tech Super Dual Auroral Radar Network (SuperDARN) operates five high-frequency (HF) radars. We are investigating cause-and-effect influences in the solar wind-magnetosphere-ionosphere system using a variety of ground- and space-based datasets. Recent research examined the north-south inter-hemispheric symmetry of the Sub-Auroral Polarization Stream (SAPS).Mapping polar ionospheric field-aligned currentsAn ECE investigation examined how the currents flowing in and out of the ionosphere respond to the interplanetary electric field, the product of the solar wind velocity and Earth’s magnetic field. We found that the magnetic field-aligned currents have a linear response to the level of solar wind driving, which was surprising since the electric fields in the ionosphere have been known to level off, or saturate, as the interplanetary electric increases.
