This work explores the dynamics of the momentum and energy of propagating mesospheric gravity waves (GWs). A photometer was used to observe the vertical component of the GWs, whereas the horizontal component was observed by an all-sky imager. Using the parameters from these two instruments and background wind from meteor radar, the momentum flux and potential energy of the GWs were determined and studied. It is noted that the dynamics of the downward-propagating GWs were controlled by observed ducts.

We studied how the Intertropical Convergence Zone (ITCZ) interacts with atmospheric gravity waves high in the sky and how global climate patterns like El Niño affect them. Using RO, ERA5, and NCEP reanalysis data, we found that the ITCZ shifts with seasons but stays strong year-round, influencing weather and energy flow. Our findings show how climate patterns shape weather systems and help predict changes, improving understanding of the atmosphere and its effects on global climate.

This present work investigates the propagation dynamics and the sources–source mechanisms of quasi-monochromatic gravity waves (QMGWs) observed between April 2017 and April 2022 at São Martinho da Serra. The QMGW parameters were estimated using a 2D spectral analysis, and their source locations were identified using a backward ray-tracing model. Furthermore, the propagation conditions, sources, and source mechanisms of the QMGWs were extensively studied.

This work investigates the sources of concentric gravity waves (CGWs) excited by a moving system of clouds with several overshooting regions on 1–2 October 2019 at São Martinho da Serra. The parameters of these waves were estimated using 2D spectral analysis and their source locations identified using backward ray tracing. Furthermore, the sources of these waves were properly identified by tracking the individual overshooting regions in space and time since the system of clouds was moving.

In the present work, the lunar semidiurnal tide (M2) was investigated in the equatorial plasma bubble (EPB) zonal drifts over Brazil from 2000 to 2007. On average, the M2 contributes 5.6 % to the variability of the EPB zonal drifts. A strong seasonal and solar cycle dependency was also observed, the amplitudes of the M2 being stronger during the summer and high solar activity periods.

This study explores intense concentric gravity waves (CGWs) based on ground-based and multi-satellite observations over southern Brazil, revealing significant airglow perturbations and strong momentum release. Triggered by deep convection and enabled by weaker wind fields, these CGWs reached the mesopause and thermosphere. Consistent detection via OI and OH airglow emissions confirms their vertical propagation, while asymmetric thermosphere propagation is linked to Doppler-induced wavelength changes.

This work analyzes the medium-scale atmospheric gravity waves observed by ground-based airglow imaging over the Antarctic continent. Medium-scale gravity waves refer to waves larger than 50 km of horizontal wavelength, and have not been analyzed in that region so far. Wave parameters and horizontal propagation characteristics were obtained by a recently improved methodology and are described thoroughly.

In this paper, atmospheric responses to the 23 October 2023 annular solar eclipse is discussed considering almost simultaneous temperature measurements from the TIMED/SABER satellite. Reductions of the temperature in troposphere, mesosphere and mesopause were observed. On the other hand, the temperature increased by about 7 K around 33 km. The temporal and spatial configuration of the measurements is consistent with the observed structures.

Comparisons of wind measurements using two different techniques (ground-based radar and satellite) in Brazil during 2006 were made in order to point out the advantages of each instrument for studies in the mesosphere and upper thermosphere. (i) For short-period variations, the measurements of the satellite were more advantageous. (ii) The monthly climatology using the radar was more appropriate. (iii) For long periods (longer than a few months), both instruments responded satisfactorily.

New low-cost, off-the-shelf Global Navigation Satellite System (GNSS) receivers enable the estimation of zonal ionospheric irregularity drifts using the scintillation spaced-receiver technique, previously tested only with commercial GNSS receivers. Despite their low C/No resolution (1 dB-Hz), we demonstrate that the recorded raw data can be used to estimate irregularity drifts. Further, our observations are consistent with the behavior of an empirical model of the thermospheric winds (HMW14).

A new algorithm for medium-scale gravity waves analysis was developed for studies of gravity waves observed by airglow imaging. With this procedure, observation datasets can be analyzed to extract the gravity waves parameters for climatological purposes. The procedure showed reliable performance and are ready to be used in other observation sites.

This study showed the ionospheric response over low-latitude regions in Brazil predicted by Martínez-Ledesma et al. (2020) for the solar eclipse event on 14 December 2020. We used a multi-instrumental and modeling analysis to observe the modifications in the E and F regions and the Es layers over Campo Grande and Cachoeira Paulista. The results showed that solar eclipses can cause significant ionosphere modifications even though they only partially reach the Brazilian low-latitude regions.

Long- and short-period oscillations in the lunar semidiurnal tidal amplitudes in the ionosphere derived from the total electron content were investigated over Brazil from 2011 to 2014. The results showed annual, semiannual and triannual oscillations as the dominant components. Additionally, the most pronounced short-period oscillations were observed between 7 and 11 d, which suggest a possible coupling of the lunar tide and planetary waves.

Short summary
Solar atmospheric tides are natural oscillations of 24, 12, 8... hours that contribute to the circulation of the atmosphere from low to high altitudes. The Sun heats the atmosphere periodically because, mainly, water vapor and ozone absorb solar radiation between the ground and 50 km height during the day. Tides propagate upward and they can be observed in, for example, the wind field. This work presents diurnal tides observed by meteor radars which measure wind between 80 and 100 km height.

Short summary
We observed two different wave propagations in the earth’s upper atmosphere: a gravity wave in the mesosphere and the ionospheric disturbances. We investigated the wave propagations by using airglow imaging techniques. It is found that there was a gravity wave generation from the tropospheric convection spot, and it propagated upward in the ionosphere. This reports observational evidence of gravity wave propagation from the troposphere to ionosphere.
