P2-ll Gravity Wave Activity in the Equatorial Middle Atmosphere Observed with a Rayleigh Lidar in India
The radar observations including radar Hauchercorne and Chanin showed that Rayleigh lidar observations are effective to measure the middle atmosphrer,especially at the altitude from 30km to 60km that cannot be observed by radars[Chanin and Hauchercorne, 1984]. Gravity waves in the middle atmosphere have been studied by investigating density and temperature fluctuations observed with Rayleigh Li...
متن کاملProperties of the Long-Term Oscillations in the Middle Atmosphere Based on Observations from TIMED/SABER Instrument and FPI over Kelan
The properties of the long-term oscillations in the middle atmosphere have been investigated using the Sounding of the Atmosphere using Broadband Emission Radiometry (SABER) temperature data and Fabry–Perot interferometer (FPI) data. Results for SABER temperature show that the semiannual oscillation (SAO) has three amplitude maxima at altitudes of 45, 75, and 85 km, respectively, and shows prom...
متن کامل1 Properties of the long - term oscillations in the middle 2 atmosphere based on observations from 3 TIMED / SABER 4 5
The properties of the annual, semiannual and triennial oscillations (AO, SAO and TO) in 15 the middle atmosphere have been investigated using the TIMED/SABER temperature data. The 16 lomb-Scargle and wavelet spectra were used to determine the dominant oscillations in the 17 background temperature field. The AO is prominent at the mid-latitudes. The AO amplitudes 18 present an asymmetry between ...
متن کاملA collaborative study on temperature diurnal tide in the midlatitude mesopause region (41°N, 105°W) with Na lidar and TIMED/SABER observations
The na lidar-observed temperature diurnal tidal perturbations, based on full-diurnal-cycle observations from 2002 to 2008, are compared with tidal wave measurements by the TIMED/SABER instrument to elucidate the nature of diurnal tidal-period perturbations observed locally. The diurnal amplitude and phase profiles deduced by the two instruments are in very good agreement most of the year. Howev...
متن کاملPerformance Assessment of Mobile Rayleigh Doppler Lidars for Middle Atmosphere Research
Recently, two sets of mobile Rayleigh Doppler lidars were implemented in University of Science and Technology of China (USTC) for atmospheric gravity waves research. One of them works in a step stare scanning mode with azimuths corresponding to four cardinal points, while the other one consists of three fixed subassemblies: one points to the zenith and the two others are titled at 30° from the ...
