Concentric gravity waves over northern China observed by an airglow imager network and satellites
Journal of Geophysical Research D: Atmospheres, 2015 The first no‐gap OH airglow all‐sky imager network was established in northern China in February 2012. The network is composed of six all‐sky airglow imagers that make observations of OH airglow gravity waves and cover an area of about 2000 km east and ...
