Stratospheric observations of noctilucent clouds: a new approach in studying large-scale wave dynamics in the middle atmosphere

Abstract
The experimental campaign Stratospheric Observations of Noctilucent Clouds (SONC) was conducted on the night of 5-6 July 2018 with the aim to photograph noctilucent clouds (NLC) and to study their large-scale spatial dynamics at scales of more than 100 km. A high-resolution camera was lifted by a stratospheric sounding balloon to 20.4 km altitude above the Moscow region in Russia. The SONC camera captured a large-scale NLC field modulated by atmospheric gravity waves of various scales. The combination of a high-resolution camera and large geographic coverage has provided a unique technique of NLC observations from the stratosphere, which is impossible to currently achieve either from the ground or space. Some preliminary results are discussed.
