Height vs. latitude structures of Q6DW zonal wind amplitudes

Simulations of prominence eruption preceded with large amplitude longitudinal oscillations and draining

An MHD simulation of the evolution of a prominence-forming twisted coronal flux rope, for which large amplitude longitudinal (LAL) oscillations are excited during the quasi-static rise phase, followed by prominence draining towards the flux rope foot-points and the eventual eruption of the flux rope and the prominence

Impact of GOLD Retrieved Thermospheric Temperatures on a Whole Atmosphere Data Assimilation Model

Comparison of the whole atmosphere temperature profiles from the true state, lower atmosphere only assimilation (LA), and lower-atmosphere plus GOLD assimilation (LA+GOLD) for 14 UT (left column) and 18 UT (right column) at different locations inside the GOLD field of view (top) and for the zonal mean (bottom)
