    "During the last decade, a very small-standardized satellite, the Cubesat, emerged as a low-cost fast-development tool for space and technology research. Although its genesis is related to education, the change in paradigm ...
  • Sherwood, P.; Veliz, O.; Meriwether, J.; Faivre, M.; Fesen, C. (Instituto Geofísico del Perú, 2008-03-26)
    "Optical observations of thermospheric winds and temperatures determined with high resolution measurements of Doppler shifts and Doppler widths of the OI 630-nm equatorial nightglow emission have been made with improved ...
  • Ambili, K. M.; Choudhary, R. K.; St.-Maurice, J. P.; Chau, Jorge L. (Instituto Geofísico del Perú, 2013-10-23)
    "The absence of photoionization, in combination with sustained downward plasma motion at night, means that the F region can be severely depleted at the magnetic equator in the morning. As a result, at sunrise, there can ...
  • Woodman P., Ronald (Instituto Geofísico del Perú, 1997)
    Ultimamente se ha producido una polémica en la que los pesqueros cuestionan la reciente decisión del Gobierno de declarar una veda a la pesca de anchoveta en toda la costa del Perú. Se argumenta que "nunca en los 30 años ...
  • Woodman Pollitt, Ronald (1997-07-05)
    Los avances de la ciencia sobre el fenómeno de El Niño - producto de los esfuerzos internacionales que se inician con el año 72 por el impacto que éste tuvo en el mercado de proteínas baratas y luego, en 1983, por las ...
  • Tavera, Hernando (Instituto Geofísico del Perú, 2018)

  • Lagos, P.; Silva, Y.; Nickl, E.; Mosquera, K. (Advanecs in Geosciences, 2008-04)
    " The relationship between monthly mean sea surface temperature (SST) anomalies in the commonly used El Niño regions and precipitation for 44 stations in Perú is documented for 1950–2002. Linear lag correlation analysis ...
  • Woodman Pollitt, Ronald (1990)
    Entrevista al Dr. Ronald Woodman Pollit, presidente ejecutivo del Instituto Geofísico del Perú, en la cual explica el fenómeno del Niño.
  • Montecinos, A; Kurgansky, M; Muñoz, C; Takahashi, K. (Instituto Geofísico del Perú, 2011-01-15)
    "The first principal component (PC1) of seasonal rainfall anomalies in central Chile during winter (June–August) is used to analyze the circulation anomalies related to wet and dry conditions, when near-normal or neutral ...
  • Sugar, G.; Oppenheim, M. M.; Bass, E.; Chau, J. L. (Instituto Geofísico del Perú, 2010-12-30)
    "High-power large-aperture (HPLA) radars frequently observe nonspecular meteor trail echoes that result from plasma turbulence driven by the intense pressure gradients on the trail edges. This paper analyzes the altitude ...
  • Woodman, R.; Kudeki, E. (1987)
    This is the only observable that the Jicamarca incoherent scatter radar was missing from the list of important parameters which define the state of the ionosphere.
  • Woodman, R.; Kohl, H. (1976-09)
    In the analysis of narrowband signals, for instance radio signals, one normally uses a complex correlation function. A question is usually asked on the relationship of this complex function and the real functions of the ...
  • Klimenko, M. V.; Klimenko, V. V.; Ratovsky, K. G.; Goncharenko, L. P.; Sahai, Y.; Fagundes, P. R.; Jesus, R. de; Abreu, A. J. de; Vesnin, A. M. (Radio Science, 2011-05-27)
