The Jicamarca Radio Observatory (JRO) is t … The Jicamarca Radio Observatory (JRO) is the equatorial anchor of the Western Hemisphere chain of Incoherent Scatter Radar (ISR) observatories extending from Lima, Peru to Søndre Strømfjord, Greenland. JRO is the premier scientific facility in the world for studying the equatorial ionosphere. The observatory is about half an hour drive inland (east) from Lima and 10 km from the Central Highway (11°57′05″S 76°52′27.5″W / 11.95139°S 76.874306°W, 520 meters ASL). The magnetic dip angle is about 1°, and varies slightly with altitude and year. The radar can accurately determine the direction of the Earth's magnetic field (B) and can be pointed perpendicular to B at altitudes throughout the ionosphere. The study of the equatorial ionosphere is rapidly becoming a mature field due, in large part, to the contributions made by JRO in radio science. JRO's main antenna is the largest of all the incoherent scatter radars in the world. The main antenna is a cross-polarized square array composed of 18,432 half-wavelength dipoles occupying an area of approximately 300m x 300m. The main research areas of the observatories are: the stable equatorial ionosphere, ionospheric field aligned irregularities, the dynamics of the equatorial neutral atmosphere and meteor physics. The observatory is a facility of the Instituto Geofísico del Perú operated with support from the US National Science Foundation Cooperative Agreements through Cornell University.ive Agreements through Cornell University.

El ROJ es la primera facilidad científica en el mundo para el estudio de la ionosfera ecuatorial. El Observatorio se ubica a media hora de viaje en automóvil hacia el este de Lima y a 10 km de la Carretera Central. Su ángulo de inclinación magnética es aproximadamente 1º, pero varía ligeramente con la altitud y la estación del año. El radar puede determinar la dirección del campo magnético terrestre (B) con gran precisión y puede ser apuntado perpendicularmente a B en las altitudes a lo largo de la ionósfera. El estudio de la ionósfera ecuatorial ha logrado un gran desarrollo debido, en gran parte, a las contribuciones realizadas por el ROJ en radio-ciencia. La antena principal del radar del ROJ es la más grande entre los radares de dispersión incoherente en el mundo, la cual consiste en un arreglo cuadrado de 300 m × 300 m y está conformada por 18,432 antenas dipolo. Las principales áreas de investigación del observatorio son: la ionosfera ecuatorial estable, irregularidades del campo alineado ionosférico, dinámica de la atmósfera ecuatorial neutra y física de meteoros. El observatorio es una instalación del Instituto Geofísico del Perú, el cual es operado con el apoyo de la US National Science Foundation a través de un acuerdo cooperativo con la Universidad Cornell.do cooperativo con la Universidad Cornell.
