Clear differences from the correct Cagniard plane wave value can occur at periods larger than about 1 min. It is further indicated that changing values of the parameters included in the electrojet model may essentially affect the source effect distortion, which complicates an estimation of the distortion. Thus it is very difficult to extract information about the Earth's conductivity structure from magnetotelluric measurements influenced by electrojet currents. In order not to overestimate the source effects, models in which the electromagnetic field, which is produced by an electrojet system, is superposed on a background field are also discussed. As expected, the source effect distortion then becomes clearly smaller in the apparent resistivity, but it does not vanish.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1381137046515684480","@type":"Researcher","foaf:name":[{"@value":"Risto Pirjola"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"00486604"},{"@type":"EISSN","@value":"1944799X"}],"prism:publicationName":[{"@value":"Radio Science"}],"dc:publisher":[{"@value":"American Geophysical Union (AGU)"}],"prism:publicationDate":"1992-07","prism:volume":"27","prism:number":"4","prism:startingPage":"463","prism:endingPage":"468"},"reviewed":"false","dc:rights":["http://onlinelibrary.wiley.com/termsAndConditions#vor"],"url":[{"@id":"https://api.wiley.com/onlinelibrary/tdm/v1/articles/10.1029%2F92RS00852"},{"@id":"https://agupubs.onlinelibrary.wiley.com/doi/pdf/10.1029/92RS00852"}],"createdAt":"2008-02-06","modifiedAt":"2023-09-23","relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1050287142202559232","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Altitude effects of localized source currents on magnetotelluric responses"}]},{"@id":"https://cir.nii.ac.jp/crid/1390001206510223232","@type":"Article","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Magnetotelluric source effect due to 3D ionospheric current systems using the complex image method for 1D conductivity structures"}]},{"@id":"https://cir.nii.ac.jp/crid/1390001206512887424","@type":"Article","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Multisheet modelling of the electrical conductivity structure in the Fennoscandian Shield"}]},{"@id":"https://cir.nii.ac.jp/crid/1390282681485919104","@type":"Article","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Behaviour of magnetotelluric source fields within the equatorial zone"}]}],"dataSourceIdentifier":[{"@type":"CROSSREF","@value":"10.1029/92rs00852"},{"@type":"CROSSREF","@value":"10.1186/bf03353045_references_DOI_IEf6UtsdoJ4Vg6vVP2WP5M76fvU"},{"@type":"CROSSREF","@value":"10.1186/s40623-020-01200-7_references_DOI_IEf6UtsdoJ4Vg6vVP2WP5M76fvU"},{"@type":"CROSSREF","@value":"10.1186/bf03351564_references_DOI_IEf6UtsdoJ4Vg6vVP2WP5M76fvU"},{"@type":"CROSSREF","@value":"10.1186/bf03351585_references_DOI_IEf6UtsdoJ4Vg6vVP2WP5M76fvU"}]}
