This study systematically investigated how a 1-hectare site selected in Tosontsengel soum meets international standards for constructing a geomagnetic observatory. We measured the geomagnetic field exactly along the predefined profiles at the site before and after construction, produced maps showing the distribution of anomalous geomagnetic fields, and compared these maps to evaluate changes and stability. Using these data, 3D models of the site’s magnetic sensitivity were also created pre- and post-construction to assess its spatial variation. The results indicate that the selected 1-hectare site in Tosontsengel soum complies with international standards for building a geomagnetic observatory, fulfilling the essential requirement of using reinforcement, cement, and insulation materials free of ferromagnetic substances. This methodology can also be applied in the future to monitor environmental magnetic contamination.
