| الوصف: | We estimate the momentum fluxes of short-period gravity waves which are observed in the OI 557.7 nm nightglow emission with all-sky camera at Mt. Bohyun (36.2° N, 128.9° E) in Korea. The intrinsic phase speed (C_{int}), the intrinsic period (τ_{int}), and vertical wavelength (λ_z) are also deduced from the horizontal wavelength (λ_h), observed period (τ_{ob}), propagation direction (φ_{ob}), observe phase speed (υ_{ob}) of the gravity wave on the all-sky images. The neutral winds to deduce intrinsic wave parameters are measured with Fabry-Perot interferometer on Shigaraki (34.8° N, 13.1° E) in Japan. We selected 5-nights of observations during the period between July 2002 and December 2006 considering of the weather and instrument conditions in two observation sites. The mean values of intrinsic parameter of gravity waves are (τ_{int}) = 12.9 ± 6.1 m/s, (λ_z) = 12.9 ± 6.5, and (C_{int}) = 40.6 ± 11.6 min. The mean value of calculated momentum fluxes for four nights besides of λ_z < 6 km is 12.0 ± 15.2 m^2/s^2. It is needed the long-term coherent observation to obtain typical values of momentum fluxes of the mesospheric gravity waves using all-sky camera and the neutral wind measurements. |
