[PEM06-P07] Performance evaluation of low-cost airglow camera for mesospheric gravity wave measurements
In this study, we newly developed a low-cost airglow camera to enlarge the airglow imaging network (Optical Mesosphere and Thermosphere Imagers: OMTIs) operated by the Solar-Terrestrial Environment Laboratory, Nagoya University. This camera has a fish-eye lens with a 185-deg field-of-view and equipped with a CCD video camera (WATEC WAT-910HX) ; the camera is small (W35.5 x H36.0 x D63.5 mm) and inexpensive, much more than the OMTI cameras, but has a highly sensitive CCD sensor with 768 x 494 pixels. OH airglow emissions are imaged at intervals of 4 sec with 4-sec exposure.
In this presentation, we will report some results of performance evaluation of this camera based on test observations at Shigaraki (35-deg N, 136-deg E), Japan, where is one of the OMTI station. By summing 15-images (i.e., 1-min composition of the images) we recognized clear gravity wave patterns in the images with comparable quality to the OMTI's image.
