✦ Synopsis
The Halogen Occultation Experiment (HALOE) experiment, on board the Upper Atmosphere Research Satellite, uses solar occultation to measure vertical proÿles of nitric oxide (NO) up to an altitude of 130 km. The in uence of dynamics on both seasonal and diurnal time-scales is clearly seen in these observations. This study presents three-dimensional simulations of NO in the mesosphere and lower thermosphere using the Thermosphere-Ionosphere-Mesosphere-Electrodynamic General Circulation Model. The e ects of both the residual circulation and atmospheric tides are modeled, and compare well with HALOE observations. The results conÿrm that the sunrise=sunset asymmetries in HALOE data are predominantly the result of tidal vertical motions.
