• W595698103 abstract "Atmospheric structures have been observed in the Rayleigh lidar data acquired between 1993 and 2004 at Utah State University (USU). The observations pertain to the density and temperature in the mesosphere between 45 and 90 km altitude. The structures referred to arise from monochromatic Atmospheric Gravity Waves (AGWs). Previous analysis of these data have searched for and found a spectrum with a peak in the vertical wavelength 12–16 km. It has been suggested by other researchers using other types of data that there may be another peak in the spectrum at shorter wavelengths. For this study the lidar data were reanalyzed to search for such waves. To do this, the altitude resolution was reduced from 3 km to 600 m. This enabled the shortest wavelength AGW that can be examined to be reduced from 6 km to ~1.2 km, thereby significantly extending the spectrum investigated. Two additional peaks in the spectrum were found at 1.25–1.75 and 3.0–4.0 km. Introduction Theory & Methods Data Analysis & Preliminary Results Continued Research Rayleigh-scatter lidar data from the Atmospheric Lidar Observatory (ALO) at USU’s Center for Atmospheric and Space Sciences at 41.74o N, 111.81o W, 1.47 km above sea level are used to study dynamic properties of the mesosphere (45 to 90 km). This region is a difficult part of earth’s atmosphere to observe as it is above the aircraft accessible stratosphere and below airglow emissions and radar backscatter. In situ rocket observations are occasionally made, but they are expensive. ALO’s lidar is a 532-nm laser that scatters light off particles at a vertical resolution of 37.5 meters and a temporal resolution of 2 minutes during 4-10 hour nights of observation. Photons returned through a 44-cm Newtonian telescope are mechanically chopped, optically filtered, detected with a gated PMT and converted to a digital signal. Background light levels and thermionic noise are measured at 120–150 km and subtracted from the signal. The remaining component of the signal is the signal of interest. Relative density fluctuations are described in terms of vertical wavelength, period, amplitude, and vertical phase speed. Onehour and all-night integrations of density fluctuations display wave behavior measured and characterized by theoretical models of perturbation theory and thermodynamics. The methods of data reduction smooth noise and render monochromatic wave structures more clearly. The AGWs have vertical wavelengths previously measured with lidars in the 6–19 km range with a dominant peak at 12–16 km, and shorter wavelengths suggested by other research to have peaks in the distribution at specific wavelengths.
