Abstract

Atmospheric gravity waves strongly influence middle atmosphere circulation and structure by vertically transporting horizontal momentum, heat, and constituents when they experience dissipation. The Utah State University Mesospheric Temperature Mapper (MTM) can obtain propagation information of short-period gravity waves and temperature perturbation by the gravity waves in the mesosphere and lower thermosphere (MLT) region. Transported momentum flux (F_M) by the gravity waves can be calculated by the wave propagation information and background wind and temperature. However, the required resolution of key background information for the calculation of F_M is not yet clear. In this study, we compare results of F_M calculated by Na wind/temperature lidar data (exhibiting high time and vertical resolution) and by Meteor Radar (with lower resolution as compared to Na lidar but constant operation). We investigate the advantages of each method for momentum flux measurements.
