Three-dimensional modeling of equatorial spread F airglow enhancements



[1] A sequence of 630.0 nm images obtained with the Boston University all-sky imaging system at Arecibo (18.3 N, 66.7 W, 28 N mag) shows equatorial spread F (ESF) airglow depletions evolving into ESF airglow enhancements. Using a combination of a meridional wind and a converging zonal wind, the NRL ionosphere model SAMI3/ESF can reproduce ESF airglow enhancements.
