Midlatitude summer nighttime anomaly of the ionospheric electron density observed by FORMOSAT-3/COSMIC
This paper presents monthly variations of the midlatitude summer nighttime anomaly (MSNA) of the ionosphere for the first time by global observations of the FORMOSAT-3/COSMIC (F3/C) mission. The anomaly is characterized by the greater nighttime (1800 LT ~ 0200 LT) ionospheric electron density than d...
