It is shown that a carefully designed full-field instrument, despite lacking temperature stabilization, can provide vectorial and scalar data accurate to a few nT, if the raw data were postprocessed by compensating for gain temperature coefficients\u2014we show how this can be obtained by a precise calibration and long-term scalar measurements. We also show a method for suppressing nT-level spikes in the data due to nearby car traffic, by utilizing gradiometric measurement for detecting the car occurrences and by employing a linear optimization problem in order to find the parameters of the moving magnetic dipole and compensate for it. In this manner, we were able to reduce the anthropogenous noise due to car traffic while keeping as much original information as possible.<\/jats:p>","DOI":"10.1155\/2018\/1804092","type":"journal-article","created":{"date-parts":[[2018,10,15]],"date-time":"2018-10-15T19:30:30Z","timestamp":1539631830000},"page":"1-10","source":"Crossref","is-referenced-by-count":2,"title":["Improving Earth\u2019s Magnetic Field Measurements by Numerical Corrections of Thermal Drifts and Man-Made Disturbances"],"prefix":"10.1155","volume":"2018","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2549-9595","authenticated-orcid":true,"given":"Michal","family":"Jano\u0161ek","sequence":"first","affiliation":[{"name":"Department of Measurement, Faculty of Electrical Engineering, Czech Technical University in Prague, Czech Republic"}]},{"given":"Mattia","family":"Butta","sequence":"additional","affiliation":[{"name":"Department of Measurement, Faculty of Electrical Engineering, Czech Technical University in Prague, Czech Republic"}]},{"given":"Michal","family":"Vlk","sequence":"additional","affiliation":[{"name":"Institute of Geophysics, Czech Academy of Sciences, Prague, Czech Republic"}]},{"given":"Tom\u00e1\u0161","family":"Bayer","sequence":"additional","affiliation":[{"name":"Institute of Geophysics, Czech Academy of Sciences, Prague, Czech Republic"}]}],"member":"311","reference":[{"key":"1","first-page":"30","volume":"2","year":"2016","journal-title":"Journal of Indian Geophysical Union"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.5194\/gi-6-301-2017"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1088\/1757-899X\/108\/1\/012026"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1063\/1.3062961"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1186\/BF03352458"},{"first-page":"83","volume-title":"A comparison between Conrad Observatory and the old Wien Cobenzl observatory: insights into anthropogenic ground currents","year":"2016","key":"6"},{"year":"1996","key":"9"},{"first-page":"59","volume-title":"Geomagnetic results Wingst, 2001- Yearbook No. 47","year":"2007","key":"11"},{"key":"12","doi-asserted-by":"publisher","DOI":"10.1088\/0957-0233\/18\/8\/050"},{"key":"15","doi-asserted-by":"publisher","DOI":"10.4401\/ag-4631"},{"key":"17","doi-asserted-by":"publisher","DOI":"10.1088\/1757-899X\/108\/1\/012025"},{"key":"18","doi-asserted-by":"publisher","DOI":"10.3390\/s17081778"}],"container-title":["Journal of Sensors"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/js\/2018\/1804092.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/js\/2018\/1804092.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/js\/2018\/1804092.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2018,10,15]],"date-time":"2018-10-15T19:30:32Z","timestamp":1539631832000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.hindawi.com\/journals\/js\/2018\/1804092\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2018,10,15]]},"references-count":12,"alternative-id":["1804092","1804092"],"URL":"https:\/\/doi.org\/10.1155\/2018\/1804092","relation":{},"ISSN":["1687-725X","1687-7268"],"issn-type":[{"type":"print","value":"1687-725X"},{"type":"electronic","value":"1687-7268"}],"subject":[],"published":{"date-parts":[[2018,10,15]]}}}
