J.; Pi, X.; Ridley, A.; Scherliess, L.; Schunk, R. W; Sojka, J. J.; Stephens, P.; Thompson, D. C.; Weimer, D.; Zhu, L.; Anderson, D.; Chau, J. L.; Sutton, E. (Instituto Geofísico del Perú, 2014-03)
    "In order to model and predict the weather of the near‐Earth space environment, it is necessary to understand the important coupling mechanisms from the surface of the Sun to the Earth's ionosphere, including its coupling ...
  • Valladares, Cesar E.; Sheehan, Robert; Pacheco, Edgardo E. (Instituto Geofísico del Perú, 2016-11-18)
    "TEC values measured by GPS receivers that belong to the low‐latitude ionosphere sensor network (LISN) and several other networks that operate in South and Central America were used to study the characteristics and origin ...
  • Anghel, Adela; Anderson, David; Chau, Jorge; Yumoto, Kiyohumi; Bhattacharyya, Archana (Instituto Geofísico del Perú, 2013-03-21)
    The overall ionospheric variability with periods ranging from long-term, secular changes to days, hours, and even minutes and seconds, is influenced by the solar activity, geomagnetic activity, and processes originating ...
  • Woodman, R. F. (Instituto Geofísico del Perú, 2002-12)
    "...To qualify as an MST radar, the system has to be capable of obtaining echoes from the mesosphere. This requirement limits the frequency range of these radars to the lower frequencies of the VHF band, i.e., between 30 ...
  • Woodman, R. F. (Instituto Geofísico del Perú, 1972-01-01)
    "A technique has been developed to measure the electromagnetic east-west drift velocity of the F region ionosphere by means of the Jicamarca incoherent scatter radar. Results show a fairly consistent behavior from day to ...
  • Kudeki, Erhan; Milla, Marco (Instituto Geofísico del Perú, 2012-04-05)
    "The chapter is organized as follows: The working principles of ISR’s and the general theory of incoherent scatter spectrum are described in Sections 2 and 3. ISR spectral features in unmagnetized and magnetized plasmas ...
  • Hysell, D. L.; Aveiro, H. C.; Chau, J. L. (Instituto Geofísico del Perú, 2014-03-14)
    "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 ...
