Morphology and Climatology of Nighttime Periodic Ionospheric TEC Disturbances Associated With MSTIDs Over China

Space Weather
In this study, the morphology and climatology of the nighttime periodic disturbances associated with medium‐scale traveling ionospheric disturbances (MSTIDs) are investigated over the entire China sector from January 2014 to August 2017, using data from ...

Observations of MSTIDs/GWs at the F2 layer heights in the near equatorial region.

Ionospheric vertical sounding observations, using a digital ionosonde (Canadian Advanced Digital Ionosonde(CADI)) , arebeing carried out on a routine basis at Manaus (2,9 0 S; 60,0 0 W; dip latitude 6,4 N, hereafter referred to as MAN), Brazil, locatedbetween the geographic and geomagnetic dip equators, since August 2002, (Fig. 1).
