    Equatorial zonal electric fields during the 2002-2003 sudden stratospheric warming event
    (Instituto Geofísico del Perú, 2009) Olson, Michael E.; Fejer, B. G.; Stolle, C.; Chau Chong Shing, Jorge Luis; Goncharenko, L. P.
    For nearly fifty years, the Jicamarca Radio Observatory (11.95°S, 76.87°W, 2°N dip latitude) near Lima, Peru, has measured ionospheric plasma drifts. Over the last ten years, measurements of plasma drift velocities have also been measured using radar observations of the equatorial 150 km altitude región (Kudeki and Fawcett, 1993; Chau and Woodman, 2004).

    Ship-borne VHF radar for upper atmospheric research
    (Instituto Geofísico del Perú, Radio Observatorio de Jicamarca, 1996) Woodman Pollitt, Ronald Francisco; Sarango, M.F.; Soldi, H.
    We have installed a VHF radar on board the Peruvian Vessel BIC Humboldt. Most of radar componentes are similar to those used by the JULIA system at Jicamarca (receptor, transmitor, acquisition (control system). However as expected the antenna design and installation is quite different.
