Abstract
Atmospheric Gravity Wave (AGW) propagation and dissipation are important processes affecting chemical species mixing as well as energy and momentum flux in the MLT region. As part of a suite of instruments located at the Andes Lidar Observatory (ALO) in Cerro Pachón, Chile, (30.2° S 70.7° W) Utah State University (USU) operates a Mesospheric Temperature Mapper (MTM) to measure intensity and temperature perturbations associated with AGW's in the OH (~87km) and adjacent O2 airglow layers (~94km). Of particular interest are a subset of waves above the Andes which are quasi-stationary, consistent with orographic wave generation during the winter season as first reported by Smith et. al. (2009) Our subsequent study using MTM data has revealed further evidence of quasi-stationary mountain waves penetrating into the MLT region in June and July 2010. These events and their wave characteristics are summarized together with new measurements of mountain wave induced intensity and temperature perturbations.
