(A) Ionospheric density profiles versus altitude for the ion-neutral chemical model with a 0° solar zenith angle (sza, noon Titan time). The day side ionosphere is driven by photoionization. The peak electron density is 5000 cm−3 at 1050 km altitude. (B) Ion density profiles versus altitude from the ion-neutral chemical model with a 180° sza (midnight Titan time). The night side ionosphere is driven by super thermal electron impact ionization. The electron density peaks is 1300 cm−3 at 1225 km altitude. The night side ionosphere drops out below 1100 km.
