Fig. 2From: Diagnosing low-/mid-latitude ionospheric currents using platform magnetometers: CryoSat-2 and GRACE-FOHemispherically anti-symmetric components of vertical current density (i.e., IHFACs) from CryoSat-2 as a function of MLT (abscissa) and MLAT (ordinate). From top to bottom, respective panels represent combined equinoxes, June solstice, and December solstice. The ‘MAG4′ in the figure title signifies a combined solution of B-field from the three magnetometers onboard CryoSat-2Back to article page
