• español

  Se ha determinado las variaciones diurnas de la ocurrencia y de varias características de las capas esporádicas de la región E sobre Islas Argentinas (65.3ºS; 64.3ºW) para otoño, invierno, primavera y verano, tanto durante niveles de actividad solar baja como alta de los ciclos solares 21, 22 y 23. Se intenta identificar posibles variaciones interdecadales, aunque se usó equipos idénticos solo durante los ciclos 22 y 23. Parece haber diferencias reales entre ciclos, al menos para algunos tipos de Es en invierno

  The diurnal variations of Sporadic-E layer (Es) occurrence and of various Es characteristics over Argentine Islands (65.3ºS; 64.3ºW) have been determined for autumn, winter, spring and summer during both low and high solar activity level for solar cycles 21, 22 and 23. Although identical equipments were used only for cycles 22 and 23, an attempt is made to identify possible inter-decadal variations, which seem to have been documented for other locations. There seems to be true inter-cycle differences at least for some Es types during winter
