How remote can the far remote reference site for magnetotelluric measurements be?

Abstract: [1] Remote reference (RR) magnetotelluric (MT) measurements are made to reduce the bias caused by noise in electric field E and magnetic field H at a local site. RR only works when noise at a local and remote sites are uncorrelated. A study has been undertaken to find the farthest distance of a far remote site for crustal study which maintains the effectiveness of the RR technique. From theoretical studies the conditions for valid RR estimates have been obtained. The study shows that the remote site can be kep… Show more

“…These simple approaches in the time domain consist of calculating the difference and correlation of magnetic time series of distinct sites measured at the same time, regarding their distances within an acceptable range following Shalivan and Bhattacharya (). Ideally, the difference is minimal, and the correlation coefficient is at maximum for alignment, particularly for 1D situation, where the secondary fields distort in the same way.…”

“…Remote reference (RR) MT measurements were carried during 1996–97 field season over a part of the southern Archaean nucleus of EIC to map the electrical conductivity of the crust and upper mantle with reference to a fixed remote site [ Bhattacharya and Shalivahan , 1999; Shalivahan and Bhattacharya , 2001] (inset Figure 1). The measurements, both at the local and RR sites, were carried out for 18 hours using GPS clock synchronisation.…”

“…A. Stodt, unpublished report, 1980]. Subsequently, the robust M estimates (RME) [ Huber , 1981; Rousseeuw and Leroy , 1987] have been applied to estimate the impedance functions [ Egbert and Booker , 1986; Chave et al , 1987; Chave and Thompson , 1989; Jones et al , 1989; Larsen , 1989; Sutarno and Vozoff , 1989, 1991; Larsen et al , 1996; Egbert and Livelybrooks , 1996; Egbert , 1997; Shalivahan and Bhattacharya , 2002; Smirnov , 2003]. Banks [1998] has studied the effect of nonstationary noise on electromagnetic response estimates in the frequency range of 0.05–0.000167 Hz.…”
