González-Galindo, Francisco; Forget, Francois; Forbes, Jeffrey M. +4 more

The nature and origins of longitudinal density structures in Mars' thermosphere between 100 and 120 km altitude, and -30° and -75° latitude around winter solstice (Ls = 70-122°), as measured by the accelerometer on the ExoMars Trace Gas Orbiter (TGO) Mission, are investigated. The methodology consists of deducing the responsible waves by comparing…
