Electrical conductivity at mid-mantle depths estimated from the data ofSq and long period geomagnetic variations
2011
Abstract
We present results of a classical global induction analysis of thegeomagnetic variation data in the range of daily Sq variations, as well as for long period variations within the period range of about 8 to 400 days. The Sq data from 88 to 94 world observatories are processed in two ways, first by constructing and analyzing average monthly daily variations for the whole months of the International Quiet Sun Year (IQSY) 1995, and second by analyzing the individual, especially quiet Q* daily records from the same year.
