En esta tesis se ha desarrollado el primer estudio estadístico de la ocurrencia de las capas Esb sobre el Radio Observatorio de Jicamarca usando ionogramas de la Digital Portable Sounder (DPS) – 4 registrados entre 2001 y 2018. Se ha encontrado que estas capas Esb ocurren principalmente en los meses ...

We performed experiments using the 50-MHz Jicamarca radar to study the equatorial 3-m scale plasma irregularities which are responsible for the radar backscatter called 15-km echoes observed at upper E-region heights from approximately 140 to 170 km. These studies were motivated by the search for a ...

Over 100 tons of material enters the Earth’s atmosphere every day, mostly in the form of meteoroids less than a millimeter across. As a meteoroid enters the atmosphere, it ablates and forms a plasma. Radars can detect this plasma, which travels at approximately the same speed as the meteoroid, as a ...

We used extensive measurements made by the Jicamarca Unattended Long-Term Investigations of the Ionosphere and Atmosphere (JULIA) and Incoherent Scatter Radar (ISR) systems at Jicamarca, Peru during geomagnetic quiet conditions to determine the climatologies of lunar tidal effects on equatorial vertical ...

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 boundary. This chapter discusses the use of the Navy Operational Global Atmospheric ...
