“…The present paper is going to report the climatological features of the migrating semidiurnal temperature tide produced for latitudes between 50 • N and 50 • S for the period of time between January 2002 and December 2007. Recently a complementary study of the migrating diurnal temperature tide based on the same SABER measurements has been presented by Mukhtarov et al (2009). It is worth mentioning that some main features of the migrating diurnal and semidiurnal temperature tides have been already reported by Zhang et al (2006) and Forbes et al (2008).…”

“…The tidal results have been obtained by a new analysis method where the tides (migrating and nonmigrating) and the planetary waves (zonally travelling, zonally symmetric and stationary) are simultaneously extracted from the satellite data. The detailed description of this method has been presented in the complimentary study of the migrating diurnal tide reported by Mukhtarov et al (2009) and here it was only briefly summarized. The method for defining the reference noise level for the tidal waves has been briefly mentioned as well.…”

“…The data analysis method for calculating the monthly mean tidal characteristics has been described in detail in the complimentary paper of a migrating diurnal tide (Mukhtarov et al, 2009), therefore here it will be only briefly summarized. This method is composed by two steps: first, the daily characteristics of the investigated waves calculated for the entire 6-year period of time (2002)(2003)(2004)(2005)(2006)(2007) are derived, and second, the monthly mean wave characteristics are calculated by geometrical averaging of the daily wave parameters for each calendar month.…”

Abstract. The present paper is focused on the global spatial (altitude and latitude) structure, seasonal and interannual variability of the migrating semidiurnal tide derived from the SABER/TIMED temperature measurements for 6 years (January 2002-December 2007. The tidal results are obtained by a new analysis method where the tides (migrating and nonmigrating) and the planetary waves (zonally travelling and stationary) are simultaneously extracted from the satellite data. The strongest migrating semidiurnal tide has been derived at tropical latitudes (±20-30 • ) where it revealed significant amplification between May and August in the lower thermosphere of both hemispheres. On the average, the semidiurnal temperature tide is stronger in the SH (32 K) than that in the NH (30 K) and the tidal amplitudes at 110 km height are nearly a factor of 5 larger than those at 90 km. The migrating semidiurnal tide in both hemispheres revealed remarkable seasonal behavior at the altitude where it maximizes, ∼110 km in the NH and ∼115 km in the SH, indicating repeatable each year maxima exactly in May-June and August. However, while the main maximum in the NH is that in August, in the SH it is that in May. The vertical wavelengths indicated seasonal variability being larger in summer (∼38-50 km) than in winter (∼25-35 km). The seasonal behavior of the semidiurnal tide in the middle latitudes (±40 • ) is dominated by annual variability with a winter maximum in the upper mesosphere (90 km) of both hemispheres and summer one in the lower thermosphere (110 km). The NH summer maximum (June and August peaks) is much stronger than that in the SH (November and March peaks) having amplitudes of ∼23 K and ∼13-15 K respectively. The vertical wavelengths at both hemispheres indicated slight seasonal changes and a mean vertical wavelength of ∼35 km is observed during most of the year. The interannual variability of Correspondence to: D. Pancheva (dpancheva@geophys.bas.bg) the semidiurnal tide in the midlatitude lower thermosphere is at least partly connected with the stratospheric QBO as this effect is stronger in the NH.

“…So it does not appear that they have considered variations with local time (diurnal variations, tides) in their regression analysis. For both ozone and temperature, diurnal variations are relatively small below ∼ 40 km but can be the dominant form of variations in the mesosphere and lower thermosphere (see Zhang et al (2006), Mukhtarov et al (2009), andHuang et al (2010a) for temperature and Huang et al (2008band Huang et al ( , 2010b for ozone). Even in the stratosphere, variations with local time may not be negligible.…”

Ozone and temperature decadal responses to solar variability in the mesosphere and lower thermosphere, based on measurements from SABER on TIMED

et al. 2016

Abstract. We have derived ozone and temperature responses to solar variability over a solar cycle, from June 2002 through June 2014, 50 to 100 km, 48 • S to 48 • N, based on data from the Sounding of the Atmosphere using Broadband Emission Radiometry (SABER) instrument on the ThermosphereIonosphere-Mesosphere-Energetics and Dynamics (TIMED) satellite. Results with this extent of coverage in the mesosphere and lower thermosphere have not been available previously. A multiple regression is applied to obtain responses as a function of the solar 10.7 cm flux (solar flux units, sfu). Positive responses mean that they are larger at solar maximum than at solar minimum of the solar cycle. From ∼ 80 to 100 km, both ozone and temperature responses are positive for all latitudes and are larger than those at lower altitudes. From ∼ 80 to 100 km, ozone responses can exceed 10 % (100 sfu) −1 , and temperature responses can approach 4 • K. From 50 to ∼ 80 km, the ozone responses at low latitudes (∼ ±35 • ) are mostly negative and can approach ∼ negative 3 % (100 sfu) −1 . However, they are mostly positive at midlatitudes in this region and can approach ∼ 2 % (100 sfu) −1 . In contrast to ozone, from ∼ 50 to 80 km, the temperature responses at low latitudes remain positive, with values up to ∼ 2.5 K (100 sfu) −1 , but are weakly negative at midlatitudes. Consequently, there is a systematic and robust relation between the phases of the ozone and temperature responses. They are positively correlated (in phase) from ∼ 80 to 100 km for all latitudes and negatively correlated (out of phase) from ∼ 50 to 80 km, also for all latitudes. The negative correlation from 50 to 80 km is maintained even though the ozone and temperature responses can change signs as a function of altitude and latitude, because the corresponding temperature responses change signs in step with ozone. This is consistent with the idea that dynamics have the larger influence between ∼ 80 and 100 km, while photochemistry is more in control from ∼ 50 to 75 km. The correlation coefficients between the solar 10.7 cm flux and the ozone and temperature themselves from 2012 to 2014 are positive (negative) in regions where the responses are positive (negative). This supports our results since the correlations are independent of the multiple regression used to derive the responses. We also compare with previous results.

This paper presents for the first time evidence showing nonmigrating tidal variations in the mesospheric ozone (O 3 ) derived from the Sounding of the Atmosphere using Broadband Emission Radiometry/Thermosphere-Ionosphere-Mesosphere-Energetics and Dynamics (SABER/TIMED) for a full 11 year period, 2002-2012. The O 3 tidal fields are extracted from the data by the same method as the temperature tides have been derived. The spatial distribution and seasonal variability of the three strongest nonmigrating O 3 tidal variabilities, i.e., SW3, DW2, and DE3, are shown. They demonstrate repeatable presence each year. These O 3 tidal variations have large amplitudes at the seasons and latitudes for which the respective temperature (T) tides amplify, i.e., near the equator and during the equinoxes. The phases of the T and O 3 tidal signatures are out of phase above 95 km. This phase relationship no longer holds for tidal perturbations below about 90 km. The O 3 SW3 and DW2 tidal variations have similar interannual variabilities that appear to follow El Niño-Southern Oscillation variability. The O 3 DE3 tidal field, however, has a clear biyearly interannual variability as the biyearly maxima correlate with the westerly phase of the quasi-biennial oscillation in tropical stratospheric winds but only up to 2008.
