- Time variation of total electron content over Tucumán, Argentina M. Mosert R. Ezquer C. Jadur R. del V. Oviedo Ciencias de la Tierra Faraday TEC equatorial anomaly The day-to-day variability of total electron content, TEC, at Tucumán (26.9S; 294.6E; Dip: -21.1) has been studied. Thedatabase includes TEC measurements by Faraday rotation during the high solar activity period from April 1982 (R12= 114) toMarch 1983 (R12= 75). Two variability parameters have been used in the analysis: the standard deviation from the mean values sand the variability index v = (standard deviation/mean value) x100. The diurnal and seasonal variations of both variability parametershave been analyzed. A comparative analysis with the day-to-day variability of critical frequency in the F2 region, foF2, ispresented. A table of values of the relative variability v is presented in terms of seasons and typical hours. Additional studies aresuggested in order to extend the results to other geographical and geophysical conditions. 2004 artículo científico 0016-7169 https://www.redalyc.org/articulo.oa?id=56843201 en http://www.redalyc.org/revista.oa?id=568 Geofísica Internacional application/pdf Universidad Nacional Autónoma de México Geofísica Internacional (México) Num.2 Vol.43
