متن کاملMeteor-head echoes over Jicamarca
Introduction Conclusions References Tables Figures Back Close Abstract Introduction Conclusions References Tables Figures Back Close Abstract We present results of recent observations of meteor-head echoes obtained with the high-power large-aperture Jicamarca 50 MHz radar (11.95 • S, 76.87 • W) in an interfer-ometric mode. The large power-aperture of the system allows us to record more than 300...
متن کاملIsolated lower mesospheric echoes seen by medium frequency radar at 70 ◦ N , 19 ◦
We have noted sporadic instances of strong isolated reflections of medium frequency (MF) radar waves from the mesosphere from as low as 50 km altitude and have devised a set of criteria for isolating these apparently anomalous echoes from those normally occurring from progressive partial reflections in the D-region. The object of this study is to map the occurrences of such echoes facilitating ...
متن کاملObservations of meteor-head echoes using the Jicamarca 50 MHz radar in interferometer mode
We present results of recent observations of meteor-head echoes obtained with the high-power largeaperture Jicamarca 50 MHz radar (11.95 S, 76.87 W) in an interferometric mode. The large power-aperture of the system allows us to record more than 3000 meteors per hour in the small volume subtended by the 1 antenna beam, albeit when the cluttering equatorial electrojet (EEJ) echoes are not presen...
متن کاملEddy turbulence parameters inferred from radar observations at Jicamarca
Significant electron density striations, neutral temperatures 27 K above nominal, and intense wind shear were observed in the E-region ionosphere over the Jicamarca Radio Observatory during an unusual event on 26 July 2005 (Hysell et al., 2007). In this paper, these results are used to estimate eddy turbulence parameters and their effects. Models for the thermal balance in the mesosphere/lower ...
