Measurements of the O+ to H+ Transition Height and Ion Temperatures in the Lower Topside Ionosphere over Arecibo for Equinox Conditions During the 2008-2009 Extreme Solar Minimum
We present incoherent scatter radar measurements of electron density, electron and ion temperatures, and ion composition made at Arecibo Observatory during the recent extreme solar minimum of 2007–2009...

Melt Veins Help to Permit Survival of Atmospheric Entry by Shocked Meteorites
Rocks shocked to pressures above the Hugoniot Elastic Limit are very friable. Melt veins in shocked meteorites may provide the strength needed to survive passage through the Earth's atmosphere.

Determining Receiver Biases in GPS-Derived Total Electron Content in the Auroral Oval and Polar Cap Region Using Ionosonde Measurements
We will test the applicability of common numerical methods for estimating receiver DCBs in high-latitude regions and compare our CADI-calibrated GPS vertical TEC measurements to corresponding International GNSS Service IONEX-interpolated…

Evidence for Deposition of 10 Million Tonnes of Impact Spherules across Four Continents 12,800 Y Ago
We present results from one of the largest spherule investigations ever undertaken regarding spherule geochemistry, morphologies, origins, and processes of formation.

Field-Aligned Current Reconfiguration and Magnetospheric Response to an Impulse in the Interplanetary Magnetic Field by Component
In this study, we analyze an interval on 5 April 2010 where there was a strong dawnward impulse in the IMF, followed by a gradual decay in IMF magnitude at…

Retrieval of Cirrus Properties by Sun Photometry: A New Perspective on an Old Issue
In the present work, we propose a new approach that uses the total measured irradiance to derive cirrus COT and ice particle effective diameter (Deff).

High Average Power Field Emitter Cathode and Testbed for X/Ku-Band Cold Cathode TWT
A new field emitter geometry that utilizes a dielectric shield between the emitter tip and gate has been optimized to eliminate flashover in the cathode emitter cavities and improve cathode…

Electrodynamics of the High-Latitude Trough: Its Relationship with Convection Flows and Field-Aligned Currents
We present a detailed case study of the electrodynamics of a high-latitude trough observed on 8 March 2008 using multiple instruments.

Frequency-Selective Surface Coupled Metal-Oxide-Metal Diodes
In this work we investigate integrating MOM diodes with a slot antenna Frequency Selective Surface (FSS). This maximizes the electromagnetic capture area while minimizing the transmission line length which helps…
