Resumen de Comparative study of gravity wave amplitude growth obtained from lidar
Fabio Vargas Galvis, Paulo Batista, Gotao Yang, Delano Gobbi
Amplitude growth rates of monochromatic gravity waves were estimated and compared in this study by using multiple instrument measurements carried out in Brazil. Wave dynamic parameters were obtained from sodium density profiles of lidar observations in São José dos Campos (23ºS, 46ºW), while multiple airglow layer imaging provided amplitudes and wave parameters of waves over Cachoeira Paulista (23ºS, 45ºW). Growth rates of gravity waves in lidar measurements are consistent with dissipative waves. Similar characteristic were also observed in waves present in airglow images. The general saturated/damped behavior is consistent with diffusive filtering processes imposing limits to amplitude growth rates of observed waves.
