Abstract
The analysis of the horizontal and vertical parameters of internal gravity waves (IGW), recorded by two different optical methods. The first instrument is a stratospheric lidar with the possibility of vertical tracking of waves up to 60 km, the second instrument is a digital all-sky camera with an infrared filter (OH), which identify the horizontal characteristics of IGW at an altitude of 86-87 km. This paper presents an analysis of several coincidence cases for the period 2006–2008, when the instruments operated simultaneously and IGW passages were detected. The investigation of the IGW parameters such as: vertical and horizontal wavelengths, periods, phase velocities and propagation directions was made.
