“…Very recently, in an issue of the Journal of Atmospheric and Solar Terrestrial Physics (May-July, 2002), Pancheva et al (2002) provided tidal-structure results from a global-scale compaign (PSMOS, June-August solstice, 1999). There were 22 radar systems; observations were made in both hemispheres, so that summer and winter conditions were sampled; the height range of 90-95 km was selected as a compromise due to the various types of radar systems.…”

Abstract. The newly-installed MFR (medium frequencyradarAnnual climatologies involving both height and frequency versus time contour plots for periods from 8 h to 30 days, show that the changes with longitude are very significant and distinctive, often exceeding the local latitudinal variations. Comparisons with models and the recent UARS-HRDI global analysis of tides are discussed. The fits of the horizontal wave numbers of the longer period oscillations are provided in unique frequency versus time contour plots and shown to be consistent with the expected dominant modes. Annual climatologies of planetary waves (16 day, 2 day) and gravity waves reveal strong seasonal and longitudinal variations.

“…Jacobi et al (1999) assessed the variation of the semidiurnal tide using a chain involving Europe, Russia and Canada (longitudinal tidal amplitude structures were inferred in winter, with one maximum along the latitude circle, S=1); and Pancheva et al (2002) (Manson et al, 2004a) Tidal wave number analysis provided nonmigrating tides components with wave numbers s=2, 0 or 3, and 4 for the diurnal and s=1, 0 or 3 for the semidiurnal.…”

Global distributions of diurnal and semidiurnal tides: observations from HRDI-UARS of the MLT region and comparisons with GSWM-02 (migrating, nonmigrating components)

Abstract. HRDI (High Resolution Doppler Interferometer-UARS) winds data have been analyzed in 4• -latitude by 10 • -longitude cells at 96 km to obtain the global distribution of the solar-tidal amplitudes and phases. The solstices June-July (1993), December-January (1993-1994, and one equinox (September-October, 1994) are analyzed.In an earlier paper (Manson et al., 2002b) the emphasis was solely upon the longitudinal and latitudinal variations of the amplitudes and phases of the semidiurnal (12 h) and diurnal (24 h) tides. The longitudinal structures were shown to be quite distinctive, and in the case of the EW component of the diurnal tide there were typically four maxima/perturbations of amplitudes or phases around a latitude circle. In this case they tended to be associated with the locations of the major oceans. Here, a spatial complex spectral analysis has been applied to the data set, to obtain the zonal wave numbers for the tides as functions of latitude. For the diurnal tide the dominant s=1 migrating component and nonmigrating tides with wave numbers s=−3, −2, 0, 2 are identified; and for the semidiurnal tide, as well as the dominant s=2 migrating component, the spectra indicate the presence of nonmigrating tides with wave numbers s=−2, 0, 4. These wave numbers are also simply related to the global longitudinal structures in the tidal amplitudes and phases.Comparisons are made with the Global Scale Wave Model (GSWM-02), which now incorporates migrating and nonmigrating tides associated with tropospheric latent heat processes, and offers monthly outputs. For the diurnal tide the dominant nonmigrating tidal spectral feature (94 km) is for wave number s=−3; it is relatively stronger than in the HRDI winds, and produces quite consistent structures in the global tidal fields with four longitudinal maxima. Overall, the modelled 24-h tidal amplitudes are larger than observed during the equinox beyond 40 • latitude. For the semidiurnal tide, Correspondence to: A. H. Manson (manson@dansas.usask.ca) nonmigrating tides are frequently indicated in the spectra with wave numbers s=−2, 0, 6; and there are complementary longitudinal structures in the global tidal fields with two and four maxima evident. Modelled 12-h tidal amplitudes are much smaller than observed during non-winter months beyond 30 • . There is a detailed discussion of the spectral features, their seasonal variations, and the similarities with the HRDI tidal data. This discussion is in the context of the inherent limitations of the model.

“…While the application of radars operating in the MF and HF bands to investigate the neutral upper atmosphere is one of the oldest such techniques still regularly in use, the techniques have been continuously improved, largely through the availability of better hardware (e.g., Reid et al 1995;Singer et al 2008;Li et al 2012) and readily available and economical but powerful computers, and provide a robust and reliable method of obtaining wind velocities (e.g., Stubbs 1973;Pancheva et al 2002), turbulence intensities (e.g., Hocking 1983;Holdsworth et al 2001), electron densities and collision frequencies (e.g., Thrane and Piggott 1966;von Biel 1977;Friedrich and Torkar 1983;Holdsworth et al 2002;Singer et al 2011), measurements of atmospheric structure (e.g., Gregory 1956;Hall 2000), temperatures (e.g., Tsutsumi et al 1999;Holdsworth et al 2006), and measurements of energy and momentum transfer (e.g., Reid and Vincent 1987;Murphy and Vincent 1993;Placke et al 2015) in the MLT region.…”

The application of medium-frequency (MF) and high-frequency (HF) partial reflection radar to investigate the neutral upper atmosphere is one of the oldest such techniques still regularly in use. The techniques have been continuously improved and remain a robust and reliable method of obtaining wind velocities, turbulence intensities, electron densities, and measurements of atmospheric structure in the mesosphere lower thermosphere (MLT) region (50 to 110 km). In this paper, we review recent developments, discuss the strengths and weaknesses of the technique, and consider possible improvements.
