Description
Summary:The study of the electromagnetic (EM) anomaly occurring in the ionosphere prior to earthquakes has attracted researchers’ interest during the past couple of decades. Similar to other parameters of the ionosphere, the EM waves in the ionosphere can be considered as a precursor of earthquake although it is influenced more by solar than seismic activities such as earthquake. Therefore, modeling of the EM waves variation caused by solar activities is necessary for prediction of earthquakes. In this study, the magnetic data obtained from the instrument magnetic search coil (IMSC) experiment onboard the detection of electromagnetic emissions transmitted from earthquake regions (DEMETER) satellite have been used to estimate the parameters of the proposed model. Since the effect of solar on the ionosphere depends on the geographic location, the analyses are limited to the data above Iran and the parameters of proposed model are only computed in this region. The main purpose of this article is to derive the statistical distribution of the noise added to the model describing the solar effect on the magnetic waves in the ionosphere at an extremely low frequency (ELF) band ranging from a few Hz up to 10 kHz. The results show that this noise can be considered as a zero-mean Gaussian distribution with known variance.
