A Study into Data Analysis of Varying Types of Langmuir Probes
… sounding rockets for measurements in mesosphere-lower-thermosphere, and also onboard satellites to obtain data sets over an extended period of time in the ionosphere. To accommodate such different situations, many different variations of the Langmuir probe design have been made. This …

Magnetic attitude control of LAICE satellite with aerodynamic stabilization
The Lower Atmosphere Ionosphere Coupling Experiment (LAICE) is a NanoSatellite which will be performing in-situ measurements of neutral and ion densities in the mesosphere, lower thermosphere, and ionosphere and correlating them to measurements of gravity waves in the lower atmosphere. The …

Observations of Non-Migrating Tides in the Middle Thermosphere
… be an important coupling mechanism through which lower atmospheric conditions influence the variability of the near-Earth space environment. Tidal variations have been exhaustively characterized in the mesosphere/lower thermosphere and the upper thermosphere, yet it is not quite known to what …

Supernova shrapnel: nearby supernovae and dust transport in the ISM
… find that the passage of SN material through the mesosphere/lower thermosphere (MLT) is the greatest influence on the final global distribution, with ocean cycling causing lesser alteration as the SN material sinks to the ocean floor. SN distance estimates in previous works that assumed a uniform …

Sensing impacts to the Earth-ionosphere waveguide from terrestrial and space weather
The Earth's lower ionosphere forms the lower-altitude limit of space plasma near the Earth, coexisting with the neutral mesosphere-lower thermosphere at 60-150 km altitude. In-situ measurements of this region are made difficult by the significant neutral density there, preventing long-duration …

Development of ground and space based instrumentation for middle and upper atmospheric studies
… temperature in the upper atmosphere, into the lower thermosphere (>90 km). The scientific interest with this system is to obtain measurements of atmospheric tides, planetary and gravity wave amplitudes and phase in the lower thermosphere. Measurement of waves into the lower thermosphere is …

Understanding Middle Atmospheric Composition Variability from the Solar Occultation for Ice Experiment Instrument and Other Datasets
… km to ~ 100 km and consists of the Stratosphere, Mesosphere, and Lower Thermosphere. The Stratosphere, Mesosphere, and Thermosphere are bounded by pauses where the strongest changes in chemical composition, movement, density, and thermal behavior take place. While several studies in the past have …
