Paper Abstract

The CSSAR airglow imager is developed to investigate the atmospheric gravity waves near the mesopause region. The CSSAR imager consists of a fisheye with a focal length of 10.5 mm and an F number of 2.8, three pieces of lenses for collimation, two filters, an imaging lens and a scientific CCD camera with 1024x1024 array, 24x24 micros pixels. Two filters for measuring the OH Meinel band (750-850nm) airglow layer peaking at 87 km and the O2 (865nm) airglow layer peaking at 90 km are used in the imager. Preliminary observation of the all-sky OH Meinel band airglow has been done during 02:00 to 06:00 on Jan. 5th, 2009, at Hancun (39.4°N, 116.6°E), Langfang, Hebei, which is the first time to image gravity wave in China. Case study shows that one quasi-monochromatic gravity wave has the horizontal wavelength of ~19 km, observed horizontal phase velocity of ~18 m/s, horizontal propagating azimuth direction of ~269° and observed period of ~18 min.
