                         quasi-2-day wave (Q2DW) in the mesosphere and lower thermosphere 
                         during January 2015 were studied employing meteor and 
                         medium-frequency radar winds at eight sites from 23 degrees S to 
                         76 degrees S and Microwave Limb Sounder (MLS) temperature and 
                         geopotential height measurements from 30 degrees S to 80 degrees 
                         S. The event had a duration of 20-25 days, dominant periods of 
                         44-52 hr, temperature amplitudes as large as 16 K, and zonal and 
                         meridional wind amplitudes as high as 40 and 80 m/s, respectively, 
                         at middle and lower latitudes. MLS measurements enabled definition 
                         of balance winds that agreed well with radar wind amplitudes and 
                         phases at middle latitudes where amplitudes were large and 
                         quantification of the various Q2DW modes contributing to the full 
                         wave field. The Q2DW event was composed primarily of the westward 
                         zonal wavenumber 3 (W3) mode but also had measurable amplitudes in 
                         other westward modes W1, W2, and W4; eastward modes E1 and E2; and 
                         stationary mode S0. Of the secondary modes, W1, W2, and E2 had the 
                         larger amplitudes. Inferred MLS balance winds enabled estimates of 
                         the Eliassen-Palm fluxes for each mode, and cumulative zonal 
                         accelerations that were found to be in reasonable agreement with 
                         radar estimates from 35 degrees S to 70 degrees S at the lower 
                         altitudes at which radar winds were available.",
