                         resonance lidar show two unexpected features: (1) Strong positive 
                         temperature gradients are often associated with strong gradients 
                         in the sodium concentration and (2) positive temperature gradients 
                         are generally much stronger than negative ones. Although the 
                         structures we see frequently appear to be associated with gravity 
                         waves or tides, the asymmetrical temperature oscillations cannot 
                         be explained as the result of simple wave propagation. We suggest 
                         that strong positive temperature gradients correspond to regions 
                         of high atmospheric stability, where eddy diffusion is inhibited, 
                         permitting the build-up of strong gradients in temperature and 
                         minor constituent mixing ratio.",
