Remote Sensing of Earth\textquoterights Limb by TIMED/GUVI: Retrieval of thermospheric composition and temperature
The Global Ultraviolet Imager (GUVI) onboard the Thermosphere-Ionosphere-Mesosphere Energetics and Dynamics (TIMED) satellite senses far ultraviolet emissions from O and N2 in the thermosphere. Transformation of far ultraviolet radiances measured on the Earth limb into O, N2, and O2 number densities and temperature quantifies these responses and demonstrates the value of simultaneous altitude and geographic information. Composition and temperature variations are available from 2002 to 2007 ...

OVATION Prime-2013: Extension of auroral precipitation model to higher disturbance levels
OVATION Prime (OP) is an auroral precipitation model parameterized by solar wind driving. Distinguishing features of the model include an optimized solar wind-magnetosphere coupling function (dΦMP/dt) which predicts auroral power significantly better than\ Kpor other traditional parameters, the separation of aurora into categories (diffuse aurora, monoenergetic, broadband, and ion), the inclusion of seasonal variations, and separate parameter fits for each magnetic latitude (MLA ...

Progress toward forecasting of space weather effects on UHF SATCOM after Operation Anaconda
Space weather impacts on communications are often presented as a\ raison d\textquoterightetre\ for studying space weather (e.g., Solar and Space Physics: A Science for a Technological Society, 2013). Here we consider a communications outage during Operation Anaconda in Afghanistan that may have been related to ionospheric disturbances. Early military operations occurred during the peak of solar cycle 23 when ionospheric variability was enhanced. During Operation Anaconda, the Battle of Takur Gh ...

The Mesoscale Ionospheric Simulation Testbed (MIST) Regional Data Assimilation Model
The Mesoscale Ionospheric Simulation Testbed (MIST) provides a regional nowcast and forecast of electron density values and has sufficient resolution to include equatorial plasma bubbles. The SSUSI instrument on the DMSP F18 satellite has high-resolution nightly observations of plasma bubbles at 8 PM local time throughout the current solar maximum. MIST can assimilate SSUSI UV observations, GPS TEC measurements, and SCINDA S4 readings simultaneously into a single scintillation map over a region of interest. MIST also mode ...

SSUSI: A Newly Available Resource for the Upper Atmosphere Community to Study the Global Response of the Coupled Ionosphere Thermosphere System
The Global Ultraviolet Imager (GUVI) on TIMED was actually the 7th wide field of regard instrument built by APL. Five SSUSI instruments were built by APL and delivered, calibrated and ready for flight between 1994 and 1996. Another instrument, the Near Infrared Spectrograph was flown on the NASA NEAR mission using the SSUSI optical design. The first SSUSI flight was in 2003 on the DMSP F16 spacecraft. Two others have flown since then on DMSP F17 and F18. Two more await flight with the next slated for a Spring 2014 launch ...
