Storm-time equatorial thermospheric dynamics and electrodynamics

Navarro Dominguez, Luis A. (Utah State University, 2020)

It presents the first comprehensive study of the equatorial thermospheric dynamics and ionospheric electrodynamics over Peru following enhanced energy depositions into the high-latitude ionosphere during geomagnetic storms. ...

A whole atmosphere model simulation of the impact of a sudden stratospheric warming on thermosphere dynamics and electrodynamics

Fuller‐Rowell, T.; Wu, Fei; Akmaev, Rashid; Fang, T. W.; Araujo‐Pradere, Eduardo (American Geophysical Union, 2010-10-15)

A Whole Atmosphere Model (WAM) has been used to explore the possible physical connection between a sudden stratospheric warming (SSW) and the dynamics and electrodynamics of the lower thermosphere. WAM produces SSWs naturally ...

Measurements of the dynamics and coupling of the equatorial thermosphere and the F-region ionosphere in Peru

Bioni, M.A.; Fejer, B.; Woodman Pollitt, Ronald Francisco; Meriwether Jr., J. W. (Elsevier, 1988)

Simultaneous Fabry-Perot Interferometer (FPI) and Incoherent Scatter Radar (ISR) observations from Arequipa and Jicamarca, Peru, respectively, were obtained on 24 and 25 September 1986, during which there was substantial ...

Modeling the low-latitude thermosphere and ionosphere

Fesen, C. G.; Hysell, D. L.; Meriwether, J. M.; Mendillo, M.; Fejer, B. G.; Roble, R. G.; Reinisch, B. W.; Biondi, M. A. (Elsevier, 2002-08)

The National Center for Atmospheric Research thermosphere/ionosphere/electrodynamic general circulation model (TIEGCM) is one of the few models that self-consistently solves the coupled equations for the neutral atmosphere ...

Thermosphere-ionosphere disturbances during two intense geomagnetic stormsThermosphere-ionosphere disturbances during two intense geomagnetic storms

Mansilla, Gustavo A.; Laboratorio de Ionosfera - Departamento de Física, Universidad Nacional de Tucumán Av. Independencia 1800 4000-San Miguel de Tucumán, Argentina (Instituto de Geofísica, 2012)

Optical interferometric measurements of nighttime equatorial thermospheric winds at Arequipa, Peru

Meriwether Jr., J. W.; Moody, J. W.; Biondi, M. A.; Roble, R. G. (American Geophysical Union, 1986-05-01)

We obtained nighttime measurements of equatorial thermospheric wind dynamics at Arequipa, Peru, with an automated field-widened Fabry-Perot interferometer between April 1983 and August 1983 and reduced data from 62 nights. ...

Stormtime dynamics of the global thermosphere and equatorial ionosphere

Burke, W. J.; Huang, C. Y.; Sharma, R. D. (European Geosciences Union, 2009-05-05)

During magnetic storms the development of equatorial plasma bubbles (EPBs) and distributions of thermospheric densities are strongly influenced by the histories of imposed magnetospheric electric (εM) fields. Periods of ...

First meteor radar observations of tidal oscillations over Jicamarca (11.95° S, 76.87° W)

Guo, L.; Lehmacher, G. (European Geosciences Union (EGU), 2009-06)

Tidal oscillations in the equatorial mesosphere and lower thermosphere (MLT) region over Jicamarca (11.95° S, 76.87° W) are studied using the observations from the newly installed Jicamarca All-sky Specular MEteor Radar ...

CEDAR Electrodynamics Thermosphere Ionosphere (ETI) Challenge for systematic assessment of ionosphere/thermosphere models: NmF2, hmF2, and vertical drift using ground‐based observations

Shim, J. S.; Kuznetsova, M.; Rastätter, L.; Hesse, M.; Bilitza, D.; Butala, M.; Codrescu, M.; Emery, B.; Foster, B.; Fuller-Rowell, T.; Huba, J.; Mannucci, A. J.; Pi, X.; Ridley, A.; Scherliess, L.; Schunk, R. W.; Stephens, P.; Thompson, D. C.; Zhu, L.; Anderson, D.; Chau Chong Shing, Jorge Luis; Sojka, J. J.; Rideout, B. (American Geophysical Union, 2011-12-31)

Objective quantification of model performance based on metrics helps us evaluate the current state of space physics modeling capability, address differences among various modeling approaches, and track model improvements ...

Early morning equatorial ionization anomaly from GOLD observations

Laskar, F. I.; Eastes, R. W.; Martinis, C. R.; Daniell, R. E.; Pedatella, N. M.; Burns, A. G.; McClintock, W.; Goncharenko, L. P.; Coster, A.; Milla, Marco; Wang, W.; Valladares, C. E.; Codrescu, M. V. (American Geophysical Union, 2020-07)

During geomagnetically quiet and solar minimum conditions, spatial variations of the early morning thermosphere‐ionosphere (TI) system are expected to be mainly governed by wave dynamics. To study the postmidnight dynamical ...
