Coupled Thermosphere Ionosphere Plasmasphere Modelwith self-consistent Electrodynamics (CTIPe)

• Global thermosphere 80 - 500 km, solves momentum, energy, composition, etc. Vx, Vy, Vz, Tn, O, O2, N2, ….

• High latitude ionosphere 80 -10,000 km, solves continuity, momentum, energy, etc. O+, H+, O2

+, NO+, N2+, N+, Vi, Ti, ….

• Plasmasphere, and mid and low latitude ionosphere

• Self-consistent electrodynamics

• Forcing: solar UV and EUV, Weimer electric field, TIROS/NOAA auroral precipitation, tidal forcing
