    Southern-hemisphere PMSE: Where are they?
    (American Geophysical Union, 1993-09) Balsley, B. B.; Woodman Pollitt, Ronald Francisco; Sarango, M.; Urbina, J.; Rodríguez, R.; Ragaini, E.; Carey, J.
    We report a surprising absence of PMSE (Polar Mesospheric Summer Echoes) in VHF radar observations of the southern summer high-latitude mesosphere. Our observations cover about twenty days during January-February, 1993, from King George Island, Antarctica.

    Wind profile radar for study of Antarctic air circulation
    (Springer, 1992-10-01) Ragaini, E.; Sarango, M.; Vásquez, E.
    After a brief discussion of meteorological methods used in the Antarctic, the paper gives an outline of a coordinated international research project whose objective is to set up a wind profiler radar station that would give meteorologists information regarding Antarctic atmospheric dynamics useful in their investigation of the causes and effects of the hole in the ozone layer. The radar instrumentation is to provide continuous readings of wind velocity at varying altitudes above the polar continent.

    Wind profiler installed in Antarctica
    (American Geophysical Union, 1993-08) Balsley, B. B; Carey, J.; Woodman Pollitt, Ronald Francisco; Sarango, M.; Urbina, J.; Rodríguez, R.; Ragaini, E.
    A VHF (50 MHz) wind profiler was installed in Antarctica at the Peruvian Base Machu Picchu on King George Island from January 21 to 26. The wind profiler will provide a first look at atmospheric dynamics over the region. The profiler-the first of its kind in Antarctica-is a National Science Foundation sponsored cooperative project of the University of Colorado, the Geophysical Institute of Peru, the University of Piura (Peru), and the Peruvian Navy. This venture was also greatly facilitated by Peru's Comision Nacional de Asuntos Antartidos and Consejo Nacional de Ciencias y Tecnologia, with additional logis tics support provided by the Argentinean Navy and the Uruguayan Air Force.
