The Super Dual Auroral Radar Network (SuperDARN) is an international scientific radar network consisting of 35high frequency (HF) radars located in both the Northern and Southern Hemispheres. SuperDARN radars are primarily used to map high-latitude plasma convection in the F region of the ionosphere, but the radars are also used to study a wider range of geospace phenomena including field aligned currents, magnetic reconnection, geomagnetic storms and substorms, magnetospheric MHD waves, mesospheric winds via meteor ionization trails, and interhemispheric plasma convection asymmetries. The SuperDARN collaboration is composed of radars operated by JHU/APL, Virginia Tech, Dartmouth College, the Geophysical Institute at the University of Alaska Fairbanks, the Institute of Space and Atmospheri

  • 超級雙重極光雷達網絡(英語:SuperDARN,全名:Super Dual Auroral Radar Network)是一個國際性的雷達網絡,用作研究大氣層高層及電離層。該網絡在北半球共有11個雷達,在南半球共有7個,能在8至22兆赫的高頻(HF)頻段作業。該雷達用作測量電離層中等離子體密度不規則特徵的多普勒速度。 在標準模式下,各雷達掃描波束的16個方位角為3.24°,總掃描時間為1分鐘。每條波束有75個分區,各長45公里,所以每一個完整的掃描雷達能覆蓋52°的方位角和超過3000公里的範圍,即超過4×106平方千米的面積。 SuperDARN於1983年開始投入作業,第一個雷達裝置建於加拿大拉布拉多。 (zh)
  • Le Super Dual Auroral Radar Network (SuperDARN, « Super réseau de radars dual auroral ») est un réseau à usage scientifique qui comprend 35 radars à hautes fréquencessitués dans les hémisphères nord et sud de la Terre. Il sert principalement à cartographier les convections de plasmas de l'ionosphère (en haute altitude). Les instruments sont aussi utilisés pour étudier d'autres phénomènes atmosphériques, tels que les courants de Birkeland, les reconnexions magnétiques, les orages magnétiques, les ondes magnétohydrodynamiques de la magnétosphère et les vents de la mésosphère.

  • Super Dual Auroral Radar Network (SuperDARN) är ett internationellt vetenskapligt radarnätverk med radar som arbetar på hög frekvens (HF) för att främst mäta plasma-aktivitet i jonosfären. Projektet har sina rötter i experiment som gjordes i Goose Bay i Labrador i Kanada från 1983 med styrbara högfrekvensradarantenner. (sv)
