Abstract
A sequential estimator was developed for the assimilation of ground and satellite based mesosphere and lower thermosphere (MLT) wind measurements. The focus was on the capabilities of the estimator to retrieve the daily evolution of diurnal tides sampled by the thermosphere ionosphere mesosphere dynamics and energetics (TIMED) Doppler interferometer (TIDI) and by ground based wind radars. Experiments with the sequential estimator showed that tropical latitudes, and up to 90 km, diurnal planetary-scale waves were well retrieved when sampled at 4 local times daily by TIDI. Accuracy of the estimator was enhanced when ground-based radar wind data sampled at a minimum of 5 local times per day were added to the TIDI sampled database.
