Precision Gravity Tests with Atom Interferometry in Space
(Elsevier, 2013-11)
Atom interferometry provides extremely sensitive and accurate tools for the measurement of inertial forces. Op- eration of atom interferometers in microgravity is expected to enhance the performance of such sensors. This ...
Evaluation of uncertainty in gravity wave potential energy calculations through GPS radio occultation measurements
(Elsevier Sci Ltd, 2013-05)
The application of the Global Positioning System (GPS) radio occultation (RO) method to the atmosphere enables the determination of height profiles of temperature, among other variables. From these measurements, gravity ...
Observations of electric fields associated with internal gravity waves
(American Geophysical Union, 2009-02-07)
At the Jicamarca Radio Observatory, the vertical drift component yields a very accurate measure of the eastward electric field. Occasionally, this drift component displays a downward phase progression, evidence for a ...
STUDYING DIRECT AND INDIRECT EFFECTS OF IMPULSES IN POWERED AERO-GRAVITY-ASSIST MANEUVERS AROUND VENUS
(Univ Nacional Autonoma Mexico, Inst De Astronomia, 2018-10-01)
The study of aero-gravity-assisted maneuvers around Venus is the focus of the present paper. These are maneuvers that combine the passage by the gravity field of the planet with an impulsive maneuver that is applied at the ...
Studying direct and indirect effects of impulses in powered aero-gravity-assist maneuvers around venus
(2018-10-01)
The study of aero-gravity-assisted maneuvers around Venus is the focus of the present paper. These are maneuvers that combine the passage by the gravity field of the planet with an impulsive maneuver that is applied at the ...
Revaluation of Mbelek and Lachièze-Rey scalar-tensor theory of gravitation to explain the measured forces in asymmetric resonant cavities
(Springer, 2017-07)
The scalar-tensor theory of gravitation proposed by Mbelek and Lachièze-Rey has been previously shown to lead to a possible explanation of the forces measured in asymmetric resonant microwave cavities. However, in the ...
Determination of the bottom deformation from space- and time-resolved water wave measurements
(Cambridge University Press, 2017-11)
In this paper we study both theoretically and experimentally the inverse problem of indirectly measuring the shape of a localized bottom deformation with a non-instantaneous time evolution, from either an instantaneous ...
Estimation of regional evapotranspiration in the extended Salado Basin (Argentina) from satellite gravity measurements
(Springer, 2011-05)
In this study, regional evapotranspiration is estimated in a wide flatland area that includes Salado River Basin and four tributary basins by using gravity measurements of the space mission Gravity Recovery and Climate ...
Preliminary multiheight radar observations of waves and winds in the mesosphere over Jicamarca
(Elsevier, 1977-09)
The Jicamarca Radio Observatory receives strong radar echoes from the mesosphere. This paper reports preliminary results of simultaneous measurements of echo power, radial velocity, and spectral width at 12 mesospheric ...
Ionosonde observations of ionospheric disturbances due to the 15 February 2013 Chelyabinsk meteor explosion
(American Geophysical Union, 2015-10-29)
We report the results of our investigations on the potential ionospheric effects caused by the 15 February 2013 Chelyabinsk meteor explosion. We used the data from a number of digisonde stations located in Europe and Russia ...
