AB: In May 2002, Colorado State University sodium lidar was upgraded to simultaneously observe mesopause region temperature and horizontal wind on 24-hour continuous basis, weather permitting. A 14-day campaign with 9-day continuous observation was completed in the second half of September 2003. Such a long data set permits definition of solar tide, and observation of short-period planetary waves, as well as their nonlinear interactions. The data set is also poised for tidal variability study, along with the observation of medium-frequency gravity waves and of the signal resulting presumably from tide-GW interactions. A series of contour plots, resulting from various spectral filtering of temperature, zonal and meridional wind profiles with 2-km and 15-min resolution, shows qualitatively, and pictorially with clarity, the riches of atmospheric wave activities and their inter-relationships in the Mesopause region.
