Sq and EEJ—a review on the daily variation of the geomagnetic field caused by ionospheric dynamo currents

Y Yamazaki, A Maute - Space Science Reviews, 2017 - Springer
A record of the geomagnetic field on the ground sometimes shows smooth daily variations
on the order of a few tens of nano teslas. These daily variations, commonly known as Sq, are …
