| Zusammenfassung |
| In this work, an upgrade of the technique for estimating the Quiet Day Curve
(QDC) as proposed by Tanaka et al. (2007) is suggested. To validate our
approach, the QDC is estimated from data acquired by the Imaging Riometer for
Ionospheric Studies (IRIS) installed at the Southern Space Observatory
(SSO/CRS/CCR/INPE – MCT, 29°4´ S, 53°8´ W, 480 m a.s.l.),
São Martinho da Serra – Brazil. The evaluation was performed by comparing
the difference between the QDCs derived using our upgrade technique with the
one proposed by Tanaka et al. (2007). The results are discussed in terms of the
seasonal variability and the level of magnetic disturbance. Also, the cosmic
noise absorption (CNA) images for IRIS data operated at SSO was built using
both the techniques aiming to check the implications of the changes in the
methods of QDC determination on the CNA that resulted from it. |
