Mansilla Ciencias de la Tierra ionosphere Thermosphere geomagnetic storm Neutral gas composition data (molecular nitrogen N2, atomic oxygen O and argon Ar) from the Dynamic Explorer 2 satellite,and critical frequency of F2-layer obtained with ionosondes, are used to examine the response of the ionosphere-thermospheresystem during two intense geomagnetic storms on July 13, 1982 and September 21, 1982. After the initial phase of thestorms large fluctuations of O density at high and low latitudes and increases of N2 and Ar densities are produced. Increases ofN2/O ratio and negative ionospheric storms are correlated and the composition changes are produced by a storm-time circulation.It is concluded that the behavior of the ionosphere is strongly compositionally controlled at high and low latitudes a few hoursafter storm commencement. 2001 artículo científico 0016-7169 https://www.redalyc.org/articulo.oa?id=56840206 en http://www.redalyc.org/revista.oa?id=568 Geofísica Internacional application/pdf Universidad Nacional Autónoma de México Geofísica Internacional (México) Num.2 Vol.40 |
