Midlatitude nighttime enhancement in F region electron density from global COSMIC measurements under solar minimum winter condition
Ionospheric electron density profiles retrieved from the Constellation Observing System for Meteorology, Ionosphere, and Climate (COSMIC) satellites measurements from 6 November 2006 to 5 February 2007 are used to study the ionospheric nighttime electron density enhancements under winter, solar mini...
