Title : Latitudinal dependence of cosmic noise absorption in the ionosphere over the SAMA
region during the September 2008 magnetic storm
Session: S6: Ionospheric storms and Space weather effects at low and mid latitudes
Preferred type of presentation: Poster
Abstract:
In this work we present and discuss some results of latitudinal dependence in the cosmic noise
absorption (CNA) as observed by the South American Riometer Network (SARINET) operated
in the South American Magnetic Anomaly (SAMA) region, during a moderate intensity
geomagnetic storm that occurred on September 03, 2008. In our analysis, we used the data
acquired by the imaging riometers installed at São Martinho da Serra (SSO - 29.4º S, 53.1º W),
Concepcion (CON - 36.5º S, 73.0º W) and Punta Arenas (PAC - 53.0º S, 70.5º W) and by the
single beam riometer installed at Trelew (TRW - 43.1º S, 65.2º W). A comparison among the
selected riometer data showed that the mean CNA was more pronounced at SSO, which is the
site located nearest to the center of the SAMA, but the second highest value was found at the
farther station. Also, a second order polynomial curve fitting was performed in order to establish
an empirical relationship between the mean CNA and the total intensity of the geomagnetic
field at the riometer stations.
