Satellite studies have obtained long-term, global-scale depictions of diurnal tides in the middle atmosphere. However, the nature of satellite sampling is that the dynamic features are shifted Doppler-shifted by the satellite motion. As a result, the migrating tide structure is aliased into the zonal mean field for sun-synchronous satellites. Precessing satellites allow a composite picture of the dynamic field to be collected in local time that can be analyzed for diurnal or semidiurnal signals. However, these composites typically take 1-2 months to collect with two node (i.e., the ascending/descending portions of the satellite orbit) sampling. In this paper, we introduce a new method to extract the migrating tides from observations taken by a slowly precessing satellite. Specifically, we present observations of migrating tides, nonmigrating tides, and planetary waves from the lower stratosphere to the lower thermosphere as observed by TIMED/SABER. The zonal mean temperatures are then subtracted from each day of data and the perturbation fields are fitted to extract the nonmigrating tides and planetary waves. We describe the temporal variability of the migrating tide and evaluate possible nonlinear sourcing mechanisms for the nonmigrating tidal components using both observations and simulations from a mechanistic fully nonlinear dynamical model.
