A comparison of the Gurevich et al. and the Liu-Jew wake models for the ion flux around a satellite
(Elsevier, 1975-04)
Observations of ion currents obtained by a retarding potential analyzer on board the Explorer 31 Satellite were used to compare the Liu-Jew and Gurevich et al. wake models with experiment. The quantitative degree of agreement ...
The effect of conjugate photoelectron impact ionization on the pre-dawn ionosphere
(Elsevier, 1973-12)
Theoretical calculations using photoelectron fluxes measured by a soft particle spectrometer on ISIS-2 as input data show that impact ionization by photoelectrons arriving from the sunlit conjugate region is insignificant ...
The nighttime distribution of ozone in the low-latitude mesosphere
(Birkhäuser-Verlag; Birkhäuser Verlag ; Springer Science+Business Media, 1973-12)
The intensity of stars at wavelengths in the Hartley continuum region of ozone has been monitored by the University of Wisconsin stellar photometers aboard the OAO-2 satellite during occultation of the star by the earth's ...
Dynamic Stress Drop of Recent Earthquakes: Variations within Subduction Zones
(Birkhäuser Verlag; Birkhäuser Verlag Basel, ; Springer Science+Business Media, 1999-05)
—Stress drop is a fundamental parameter of earthquakes, but it is difficult to obtain reliable stress drop estimates for most earthquakes. Static stress drop estimates require knowledge of the seismic moment and fault area. ...
SMLTM simulations of the diurnal tide: comparison with UARS observations
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1997-10)
Wind and temperature observations in the mesosphere and lower thermosphere (MLT) from the Upper Atmosphere Research Satellite (UARS) reveal strong seasonal variations of tides, a dominant component of the MLT dynamics. ...
Thermal tides and studies to tune the mechanistic tidal model using UARS observations
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1997-10)
Monthly simulations of the thermal diurnal and semidiurnal tides are compared to High-Resolution Doppler Imager (HRDI) and Wind Imaging Interferometer (WINDII) wind and temperature measurements on the Upper-Atmosphere ...
Oscillations of electrostatically trapped particles
(Elsevier, 1970-01)
A kinetic theory of longitudinal ionic oscillations is presented which pertains to an earlier hypothesis that low frequency plasma oscillations monitored in the wake of Ariel I Satellite are due to ions trapped in the ...
Poker Flat MST radar observations of high latitude neutral winds at the mesopause during and after solar proton events
(Elsevier, 1993-07)
Observations with the Poker Flat, Alaska, MST radar during and after solar proton events in 1982 and 1984 suggest that winds in the altitude range of ~ 80-90 km were altered as a consequence of the influx of energetic ...
Some Aspects of Energy Balance and Tsunami Generation by Earthquakes and Landslides
(Birkhäuser-Verlag; Birkhäuser Verlag, Basel, ; Springer Science+Business Media, 2003-10)
— Tsunamis are generated by displacement or motion of large volumes of water. While there are several documented cases of tsunami generation by volcanic eruptions and landslides, most observed tsunamis are attributed to ...
Comparisons between Canadian prairie MF radars, FPI (green and OH lines) and UARS HRDI systems
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1997-10)
Detailed comparisons have been completed between the MF radars (MFR) in the Canadian prairies and three other systems: two ground-based Fabry-Perot interferometers (FPI) and the UARS high resolution Doppler imager (HRDI) ...
