“…In recent years, new ground-based instruments have been built in China to monitor the mesosphere and lower thermosphere, including the digital ionosonde [6], the meteor radar [7][8][9][10][11], and the atmosphere gravity wave imager [12] in China. Some researchers have analyzed international observational data obtained by FPIs [13].…”

A Fabry-Perot interferometer, funded by the Meridian Project in China, was deployed at the Xinglong station (40. 2°N,117.4°E) of the National Astronomical Observatories in Hebei Province, China. The instrument has been operating since April 2010, measuring mesospheric and thermospheric winds. The first observational data of winds at three heights in the mesosphere and thermosphere were analyzed, demonstrating the capacity of this instrument to aid basic scientific research. The wavelengths of three airglow emissions were OH892.0, OI 557.7, and OI 630.0 nm, which corresponded to heights of 87, 98, and 250 km, respectively. Three 38-day data sets of horizontal winds, from April 5, 2010 to May 12, 2010, show clear day-to-day variations at the same height. The minimum and maximum meridional winds at heights of 87, 98, and 250 km were -16.5 to 8.7 m/s, -24.4 to 15.9 m/s, and -43.6 to 1.5 m/s. Measurements of zonal winds were -5.4 to 7.6 m/s, 2.3 to 23.0 m/s, and -22.6 to 49.3 m/s. The average data from the observations was consistent with the data from HWM93. The wind data at heights of 87 and 98 km suggest a semi-diurnal oscillation, clearly consistent with HWM93 results. Conversely there was a clear discrepancy between the observations and the model at 250 km. In general, this Fabry-Perot interferometer is a useful ground-based instrument for measuring mesospheric and thermospheric winds at middle latitudes.

First observation of mesospheric and thermospheric winds by a Fabry-A Fabry-Perot Interferometer (FPI) uses a CCD detector to record interference patterns formed by the Fabry-Perot etalon filter. Interference patterns provide much information, such as Doppler shift and spectrum line broadening. FPIs have been used for many years worldwide to measure neutral winds and temperatures in the mesosphere and thermosphere as both ground-based and satellite-borne instruments [1-5]. Neutral winds can be derived from monitoring the night time airglow emissions of OH 892.0 nm at 87 km, OI 557.7 nm at 98 km, and OI 630.0 nm at 250 km. These observational neutral wind data are important for modeling

“…For example, regular annual variation of the wave phase was observed in the meridional wind at Wuhan (30 • N) and Wakkanai (45.4 • N) (Namboothiri et al, 2004;Zhao et al, 2005), and in the zonal wind at London, Canada (43 • N) (Thayaparan, 1997). The vertical wavelength reported by the previous studies was found to vary widely, over a range from 12 to more than 1000 km.…”

“…Nevertheless, the 8-h tide, as a distinct wave signature in the MLT region, is not well understood, especially compared to the diurnal tide and semidiurnal tide. Besides the work of Smith (2000) based on the wind measurement of High Resolution Doppler Interferometer (HRDI) instrument on the Upper Atmosphere Research Satellite (UARS), the variations of the 8-h tide have been investigated using ground-based observations in the Northern Hemisphere at middle-and high-latitude (Manson and Meek, 1986;Teitelbaum et al, 1989;Thayaparan, 1997;Pendleton et al, 2000;Younger et al, 2002;Namboothiri et al, 2004;Taori et al, 2005;Zhao et al, 2005;Beldon et al, 2006). These studies showed that the seasonal behavior of the 8-h tide in the MLT region is different at different latitudes.…”

“…Whilst several of those studies addressed the tidal effects and characteristics in the middle (e.g. Forbes, 1984) and upper atmosphere (Forbes and Garrett, 1979;Forbes, 1990;Thayaparan, 1997;Zhao et al, 2005), we concentrate, for reasons of comparability, on troposphere-based observations and theories (e.g. Haurwitz, 1956;Kertz, 1956;Dai and Wang, 1999).…”

Abstract. The International Monitoring System (IMS) has been established to monitor compliance with the ComprehensiveNuclear-Test-Ban Treaty and comprises four technologies, one of which is infrasound. When fully established, the IMS infrasound network consists of 60 sites homogeneously distributed around the globe. Besides its primary purpose of determining explosions in the atmosphere, the recorded data reveal information on other anthropogenic and natural infrasound sources. Furthermore, the almost continuous multiyear recordings of differential and absolute air pressure allow for analysing 10 the atmospheric conditions. In this paper, spectral analysis tools are applied to derive atmospheric dynamics from barometric time series. Based on the solar atmospheric tides, a methodology for performing geographic and temporal variability analyses is presented which is supposed to serve for upcoming studies related to atmospheric dynamics. The surplus value of using the IMS infrasound network data for such purposes is demonstrated by comparing the findings on the thermal tides with previous studies and the Modern-Era Retrospective analysis for Research and Applications, version 2 (MERRA-2), which well 15 represents the solar tides in its surface pressure fields. Absolute air pressure recordings reveal geographic characteristics of atmospheric tides related to the solar day and even to the lunar day. We therefore claim the chosen methodology of using the IMS infrasound network to be applicable for global and temporal studies on specific atmospheric dynamics. Given the accuracy and high temporal resolution of the barometric data from the IMS infrasound network, interactions with gravity waves and planetary waves can be examined in future for refining the knowledge of atmospheric dynamics; e.g., the origin of tidal 20 harmonics up to 9 cycles per day as found in the barometric data sets. Data assimilation in empirical models of solar tides would be a valuable application of the IMS infrasound data.
