“…Similar to results shown by Cartwright et al (1988) and Spencer and Vassie (1997), Ss is one of a series of peaks seen at integral multiples of exactly one cycle per solar day. Such lines are characteristic of the spectrum of atmospheric surface pressure (e.g., Smylie et al 1993) and represent higher harmonics of the atmospheric tide. Thus, Ss in Table 1, as well as the other Sn (n :p 2) lines evident in the BPR spectrum, are likely the combined result of the atmosphere's Sn barometric tide and the ocean's (dynamic) response to that load.…”

Seafloor pressure records, collected at 11 stations aligned along a single ground track of the Topex/Poseidon and Jason satellites, are analyzed for their tidal content. With very low background noise levels and approximately 27 months of high-quality records, tidal constituents can be estimated with unusually high precision. This includes many high-frequency lines up through the seventh-diurnal band. The station deployment provides a unique opportunity to compare with tides estimated from satellite altimetry, point by point along the satellite track, in a region of moderately high mesoscale variability. That variability can significantly corrupt altimeter-based tide estimates, even with 17 years of data. A method to improve the alongtrack altimeter estimates by correcting the data for nontidal variability is found to yield much better agreement with the bottom-pressure data. The technique should prove useful in certain demanding applications, such as altimetric studies of internal tides.

“…The steady-frequency oscillations at 64, 74, and 77 µHz have also been revealed by Karpova et al (2004) through the technique of spectra multiplication. Moreover, the 74 and 77 µHz oscillations have been earlier detected from European superconducting gravimeter measurements (Smylie et al, 1993). It appears reasonable to assume that there are atmospheric normal modes among the above-mentioned oscillations.…”

“…Using simultaneous microbarometer and superconducting gravimeter measurements with the duration no less than one year, Warburton and Goodkind (1977), Smylie et al (1993), andCrossley et al (1995) have detected subharmonics of the solar tide, S m (m is the number of cycles per day), up to m ∼ 10 (corresponding period is ∼2.5 h) in the variations of both pressure and gravity at different midlatitude sites in Europe and Northern America. The S m subharmonics up to m = 10 have also been revealed by Livneh et al (2007) from a 1-year record of surface-pressure variation at the low-latitude site Arecibo.…”

Steady-frequency waves at intradiurnal periods from simultaneous co-located microbarometer and seismometer measurements: a case study

Abstract. Simultaneous co-located microbarometer and vertical-pendulum seismometer measurements at St. Petersburg (59.9 • N, 29.8 • E) with total duration of 4 months are used to study atmospheric oscillations at steady frequencies at periods shorter than 8 h. The temporal behavior of the phase shift between oscillations detected simultaneously by both instruments is analyzed for oscillations of periods up to as short as ∼0.5 h. Some of oscillations last up to several days. For the 42-90 min and 2.5-5 h period ranges, the temporal behavior of the power spectra are considered and correlated with the atmospheric angular momentum of zonal wind, tropical cyclones and large earthquakes. Signatures of sequences of subharmonics of the solar tide are revealed with periods up to day/30. There are indications of effects of the 5-day planetary waves and tropical cyclones on wave activity in the ∼1-5 h period range. A weak increase of wave activity is observed when large earthquakes occur.

“…Smylie andMcMillan, 1998 andRieutord, 2002). However, many attempts using spectral methods and stacking processes have not yet led to the reliable detection of the surface gravity signature of the free oscillation of the inner core Hinderer et al, 1995;Rosat et al, 2003 and2006;Guo et al 2006a and2006b) while the unique observation by Smylie (1992) and Smylie et al (1993) has been confirmed by Courtier et al (2000). However, Rieutord (2002) and Rogister (2003) have demonstrated that this unique claim of detection is irrelevant to the theoretical predictions.…”
