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 …

Abstract The NASA Ionospheric Connection explorer (ICON) will study the coupling between
the thermosphere and ionosphere at low-and mid-latitudes by measuring the key …

The climatology of the equatorial electrojet during periods of enhanced geomagnetic activity
is examined using long‐term records of ground‐based magnetometers in the Indian and …

It has been known for a long time that the equatorial electrojet varies from day to day even
when solar and geomagnetic activities are very low. The quiet time day‐to‐day variation is …

This paper describes solar and lunar daily variations of the geomagnetic field over low-and
mid-latitude regions, using vector magnetometer data from Swarm satellites at altitudes of∼ …

The atmospheric lunar tide is one known source of ionospheric variability. The subject
received renewed attention as recent studies found a link between stratospheric sudden …

Abstract The Equatorial Electrojet (EEJ) is one of the important near‐earth space weather
phenomena which exhibits significant diurnal, seasonal and solar activity variations. This …

Years of geomagnetic observatory data during the geomagnetic quiet days (Kp≤ 3) at the
low and middle dip latitudes from INTERMAGNET and SuperMAG were utilized. Seasonal …

The impact of strong and weak stratospheric polar vortices on geomagnetic semidiurnal
solar and lunar tides is investigated during Northern Hemisphere (NH) winters using ground …

This study investigates the response of the Asian‐Australian low‐latitude ionosphere to the
2013 Sudden Stratospheric Warming (SSW) event. The equatorial ionization anomaly …
