MF radar measurements of sub-scale mesospheric momentum flux



[1] Measurements of Mesosphere and Lower Thermosphere (MLT) wind velocities and spectral widths made using the Buckland Park MF (1.98 MHz) Doppler radar, located near Adelaide, Australia (35°S, 138°E), have been analyzed to obtain the density normalized upward flux of zonal momentum for scales smaller than the radar pulse volume. The results indicate the presence of significant fluxes, with height profiles similar in magnitude and direction to those obtained for the same data for scales larger than the pulse volume.
