Ionospheric Irregularities: Frontiers
(American Geophysical Union, 2014-03-14)
There are several thermosphere ionosphere models with bottom boundaries somewhere in the middle atmosphere. Achieving a true whole atmosphere modeling capability requires the specification of atmospheric conditions at a ...
The Impact of Atmospheric Correction on Brazilian Earth Tide Models
(2020-09-01)
Terrestrial gravity stations have been in operation for several years throughout Brazil. Minimizing geophysical effects on gravimetric observations is a major challenge in the generation of solid Earth tide models. The ...
Jicamarca radar observations of the diurnal and semidiurnal tide in the troposphere and lower stratosphere
(American Geophysical Union, 2002-04)
The mesosphere-stratosphere-troposphere (MST) radar at Jicamarca, Peru (12S, 77W), made extended (15 day or longer) observations of the horizontal and vertical winds that were used to infer the diurnal and semidiurnal ...
First meteor radar observations of tidal oscillations over Jicamarca (11.95° S, 76.87° W)
(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 ...
Ionosphere variability during the 2009 SSW: Influence of the lunar semidiurnal tide and mechanisms producing electron density variability
(American Geophysical Union, 2014-04-23)
To investigate ionosphere variability during the 2009 sudden stratosphere warming (SSW), we present simulation results that combine the Whole Atmosphere Community Climate Model Extended version and the thermosphere-ionos ...
The semidiurnal tide for individual nights derived consistently from O 2 and OH intensities and temperatures
(Elsevier, 2019-05)
The semidiurnal tide is studied with 159 special cases from the large airglow database acquired at El Leoncito (31.8ºS, 69.3ºW). These cases correspond to nights which exhibit similar periods in the temperature and intensity ...
Unexpected connections between the stratosphere and ionosphere
(American Geophysical Union, 2010-05)
The coupling of the ionosphere to processes from below remains an elusive and difficult problem, as rapidly changing external drivers from above mask variations related to lower atmospheric sources. Here we use superposition ...
Lunar atmospheric tidal effects in the plasma drifts observed by the Low‐Latitude Ionospheric Sensor Network
(American Geophysical Union, 2011-07-21)
Data from the Low‐Latitude Ionospheric Sensor Network are used to examine ionospheric electrodynamics during quiet, low solar conditions from September to November 2009. The ground‐based magnetometers and the Jicamarca ...
Tides and wind-driven circulation in the tropical and Southern Atlantic Ocean: the BRAZCOAST system
(Institute of Atmospheric PhysicsBeijing, 2014)
The Brazilian coast is characterized by different
tidal regimes and distinct meteorological influences.
The northern part has larger tidal amplitudes and is
permanently affected by trade winds and tropical disturbances;
the ...
Climatology of mesosphere and lower thermosphere diurnal tides over Jicamarca (12°S, 77°W): observations and simulations
(SpringerOpen, 2023-12-14)
This work shows a 3-year climatology of the horizontal components of the solar diurnal tide, obtained from wind measurements made by a multistatic specular meteor radar (SIMONe) located in Jicamarca, Peru (12°S, 77°W). Our ...
