Equinoctial asymmetry in solar activity variations of <I>Nm</I>F2 and TEC

The ionosonde <I>Nm</I>F2 data (covering several solar cycles) and the JPL TEC maps (from 1998 through 2009) were collected to investigate the equinoctial asymmetries in ionospheric electron density and its variation with solar activity. With solar activity increasing, the equinoctia...
