“…Since eigen-frequencies of the oscillations were calculated for realistic atmospheric models by Haurwitz (1937), several modes have been identified in observed data (e.g. Eliasen and Machenhaur, 1965;Madden, 1978 1962-1963 and 1965-1966, in addition to the data mentioned previously.…”

“…These four tidal constituents are prominent in the oceans, although dynamical and boundary effects change their relative amplitudes at different locations. The M2 tide is the strongest component of the lunar atmospheric tide and it has been studied extensively (e.g., Haurwitz and Cowley, 1969;Chapman and .Lindzen, 1970); a recent investigation by Maimn and Chapman (1970a) revealed the existence of the O1 and N2 constituents in the atmospheric pressure.…”

Geomagnetic data from twelve stations have been analyzed for O1 lunar tidal variations by the Chapman-Miller method. Well-determined geomagnetic O1 tides were found in the vertical component at several stations. In most cases little or no solar modulation of the fundamental frequency of the O1 (Z) tide was detected, thus making an ionospheric source for the O1(Z) tide unlikely. The most probable cause of the O1(Z) variation is electric currents induced in the oceans by O1 tidal currents. No definite conclusions could be drawn about O1 tides in the horizontal component of the field because of ambiguity between genuine O1 tides and seasonal changes in the M2 geomagnetic tide.

“…20 A study of Chapman and Westfold (1956) indicated that the global distribution of the lunar semidiurnal tide is similar to that of the solar counterpart. Hence, the mean annual amplitude is maximum in equatorial regions and decreases with increasing latitude (Haurwitz and Cowley, 1969;Schindelegger and Dobslaw, 2016). Combined with its generally small amplitude (Lindzen and Chapman, 1969), this explains why distinct signatures of the lunar semidiurnal tide (Fig.…”

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.
