Abstract Since the mobile Rayleigh Doppler lidar of University Science and Technology China was developed in 2013, more than 100 days valid nighttime wind data from 15 to 60 km altitude were obtained during recent 3 years. The observation locations cover northwest (midlatitude) China: Delingha (37.371°N, 97.374°E), Xinzhou (38.425°N, 112.729°E), Jiuquan (39.741°N, 98.495°E). Recently, we have extracted perturbations profiles field measurements found that inertia gravity waves mountain...

Abstract This work presents the first lidar observations of a Quasi‐Biennial Oscillation (QBO) in interannual variations stratospheric gravity wave potential energy density ( E pm 30–50 km) at McMurdo (77.84°S, 166.67°E), Antarctica. paper also reports identification QBO signals distance between and polar vortex edge. Midwinter activity is stronger during easterly phase when June expands night jet shifts equatorward. During westerly phase, weaker contracts moves poleward. Nine years data...

A well-designed filter assembly is incorporated to an earlier mobile Rayleigh Doppler Lidar developed at University of Science and Technology China (USTC) for wind measurement round the clock. The consists two cascaded Fabry-Perot Etalons (FPEs) a narrow-band interference (IF), which are optimized out strong solar background radiation during daytime. high resolution FPE mainly used compress whole bandwidth assembly, whereas low with relatively large free spectral range (FSR) primarily block...

Speed range is an important specification of coherent Doppler wind lidar (CDWL). However, it difficult to identify the lower speed bound CDWL, because signal often overlapped or covered by relative intensity noise (RIN) at low-frequency end spectrum. Therefore, how distinguish and RIN low frequency always issue. In optical information processing, Rayleigh criterion specifies spatial resolution limit, which minimum distance between two distinguishable Airy disks. Due rigorous one-to-one...

A Scanning Rayleigh Doppler lidar for wind profiling based on a non-polarized beam splitter cube optically contacted FPI is developed measurement from high troposphere to low stratosphere in 5-35 km. Non-polarized the are used stable optical receiver. Zero shift correction correct laser or frequency jitter and drift timing sequence designed. Stability of receiver discrimination validated by measuring transmissions different days analyzed response functions. The maximal relative deviation due...
