 Recent studies on atmospheric gravity waves, AGW, and traveling ionospheric disturbances, TID, in the Earth's thermosphere and ionosphere have been reviewed. Model simulations and observation campaigns such as the worldwide atmospheric gravity wave study, WAGs, have provided insight into the generation of AGWs at high latitudes and their subsequent propagation to low latitudes. Additionally, recent advances in inversion techniques have allowed for the identification of AGW-slash-TID relationships. These advancements have led to a better understanding of the morphology and climatology of gravity waves and their ionospheric manifestations, TIDs. This article was authored by K-Hawk and K-Schlegel.
