Abstract
FLORES, P. A. and FOPPIANO, A. J.. Inter-decadal variability of Sporadic-E layer at Argentine Islands, Antarctica?. Geofís. Intl [online]. 2008, vol.47, n.3, pp.173-177. ISSN 2954-436X.
The diurnal variations of Sporadic-E layer (Es) occurrence and of various Es characteristics over Argentine Islands (65.3°S; 64.3°W) 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.
