3D measurements help understand geomagnetic storm hazards
Measurements of the three-dimensional structure of the earth, as opposed to the one-dimensional models typically used, can help scientists more accurately determine which areas of the United States are most vulnerable to blackouts during hazardous geomagnetic storms. Space weather events such as geomagnetic storms can disturb the earth’s magnetic field, interfering with electric power grids, radio communication, GPS systems, satellite ...
