Satellite traces, range spread-F occurrence, and gravity wave propagation at the southern anomaly crest
Autor: M. A. Cabrera, M. Pezzopane, E. Zuccheretti, R. G. Ezquer
Publikováno v: Annales Geophysicae, Vol 28, Pp 1133-1140 (2010)
Range spread-F (RSF) and occurrence of "satellite" traces prior to RSF onset were studied at the southern peak of the ionospheric equatorial anomaly (EA). Ionograms recorded in September 2007 at the new ionospheric station of Tucumán, Argentina (

Autor: R. G. Ezquer, G. A. Mansilla
Publikováno v: Geofísica Internacional, Vol 43, Iss 1, Pp 23-28 (2004)
Neutral gas density data of molecular nitrogen N2 and atomic oxygen O between 310 km and 330 km altitude as obtained by the Dynamic Explorer 2 satellite and ground-based foF2 data with ionosondes were used to examine the response of the thermosphere-
