Short summary
The knowledge of decadal temperature trends in the stratosphere, mesosphere, and lower thermosphere (20 to 100 km) is important for both scientific and practical reasons and for the relation to climate change. Almost all long-term measurements are made at fixed or limited local time intervals. The differences among the various measurements can be significant. Our results show that at least some of these differences may be due to the different local times at which the temperatures are measured.

Short summary
The sun’s radiation exhibits a cycle with a period of ~11 years. We need to understand how the atmospheric temperature and ozone react to this solar variation, as it can affect climate. The response depends on energy transfer, chemical reactions, and atmospheric motions. There is no consensus as to some details. For example, the responses depend on the local times of the variations. This study provides results of effects of local time on the responses, from 20 to 100 km, based on measurements.

We have derived ozone and temperature responses to solar variability over a solar cycle, from 2002 to 2014 at 20–60 km and 48°S–48°N, based on a new dataset (SABER). These global results can be directly compared with 3-D models and will help in understanding not only the physical processes but also how they affect the Earth's climate. The simultaneous measurements of ozone and temperature will give added insight into the dynamics and photochemistry of the middle and upper atmosphere.

A rare gravity wave event was observed on the night of 25 April 2017 over northern Germany. An all-sky airglow imager recorded an upward-propagating wave at different altitudes in mesosphere with a prominent wave front above 91 km and faintly observed below. Based on wind and satellite-borne temperature profiles close to the event location, we have found the presence of a leaky thermal duct layer in 85–91 km. The appearance of this duct layer caused the wave amplitudes to diminish below 91 km.

This study analyzes the quality of two versions (v3.6 and v4.1) of ozone concentration measurements from the ACE-FTS (Atmospheric Chemistry Experiment Fourier Transform Spectrometer), by comparing with data from five satellite instruments between 2004 and 2020. It was found that although the v3.6 data exhibit a better agreement than v4.1 with respect to the other instruments, v4.1 exhibits much better stability over time than v3.6. The stability of v4.1 makes it suitable for ozone trend studies.

Based on the gradient balance wind theory and the SABER observations, a dataset of monthly mean zonal wind has been developed at heights of 18–100 km and latitudes of 50° Sndash;50° N from 2002 to 2019. The dataset agrees with the zonal wind from models (MERRA2, UARP, HWM14) and observations by meteor radar and lidar at seven stations. The dataset can be used to study seasonal and interannual variations and can serve as a background for wave studies of tides and planetary waves.

Details of the driving of the semiannual oscillation (SAO) of the tropical winds in the middle atmosphere are still not known. We investigate the SAO and its driving by small-scale gravity waves (GWs) using satellite data and different reanalyses. In a large altitude range, GWs mainly drive the SAO westerlies, but in the upper mesosphere GWs seem to drive both SAO easterlies and westerlies. Reanalyses reproduce some features of the SAO but are limited by model-inherent damping at upper levels.

With airglow spectrometers, the temperature in the upper mesosphere/lower thermosphere can be derived each night. The data allow to estimate the amount of energy which is transported by small-scale atmospheric waves, known as gravity waves. In order to do this, information about the Brunt–Väisälä frequency and its evolution during the year is necessary. This is provided here for low and midlatitudes based on 18 years of satellite data.

The Nimbus 7 limb infrared monitor of the stratosphere (LIMS) instrument operated from October 25, 1978, through May 28, 1979. This note focuses on the lower stratosphere of the southern hemisphere, subpolar regions in relation to the position of the polar vortex. Both LIMS ozone and nitric acid show reductions within the edge of the polar vortex at 46 hPa near 60° S from late October through mid-November 1978, indicating that there was a chemical loss of Antarctic ozone some weeks earlier.

The Solar Occultation for Ice Experiment (SOFIE) has measured nitric oxide (NO) from satellite since 2007. The observations are validated through error analysis and comparisons with other satellite observations. Calculated SOFIE NO uncertainties are less than 50 % for altitudes from 40 to 140 km. SOFIE agrees with other measurements to within 50 % for altitudes from roughly 50 to 105 km for spacecraft sunrise and 50 to 140 km for sunsets.

In winter 2016, the camera system FAIM derived information about the OH* airglow at ca. 86 km height during six flights on board the research aircraft FALCON in northern Scandinavia. Coincident ground- and satellite-based measurements (GRIPS and TIMED-SABER) complete the data set. The data are analysed with respect to the temporal and spatial evolution of small-scale atmospheric dynamics just before a minor stratospheric warming. Special emphasis is placed on possible instability features.

A model was developed to derive night-time atomic oxygen (O(3P)) and atomic hydrogen (H) from satellite observations in the altitude region between 75 km and 100 km. Comparisons between the
best-fit modeland the measurements suggest that chemical reactions involving O2 and O(3P) might occur differently than is usually assumed in literature. This considerably affects the derived abundances of O(3P) and H, which in turn might influence air temperature and winds of the whole atmosphere.

We use data from two NASA satellites and a general circulation model of the upper atmosphere to elucidate the key factors governing the abundance and diurnal variation of nitric oxide (NO) at near-solar minimum conditions and low latitudes. This has been difficult to do previously, because NO data are typically taken from satellites in sun-synchronous orbits, meaning that they only acquire data in fixed local times. We overcome this limitation through model simulations of the NO diurnal cycle.

Trend estimates of lower stratospheric H2O derived from the FPH observations at Boulder and a merged zonal mean satellite data set clearly differ for the time period from the late 1980s to 2010. We investigate if a sampling bias between Boulder and the zonal mean around the Boulder latitude can explain these trend discrepancies. Typically they are small and not sufficient to explain the trend discrepancies in the observational database.

OH*-spectrometer measurements allow the analysis of gravity wave ground-based periods, but spatial information cannot necessarily be deduced. We combine the approach of Wachter at al. (2015) in order to derive horizontal wavelengths (but based on only one OH* spectrometer) with additional information about wind and temperature and compute vertical wavelengths. Knowledge of these parameters is a precondition for the calculation of further information such as the wave group velocity.

Typical distributions of multiple GW parameters are provided. Possible applications are scientific studies, comparison with other observations, or comparison with resolved or parametrized GW distributions in models.

There is a massive manifestation of atmospheric gravity waves (GWs) in polar mesospheric clouds (PMCs) at the summer mesopause, which serves as indicators of the atmospheric dynamics and climate change. We obtained a universal power law that governs the GW display morphology and clarity level throughout the wave population residing in PMCs. Higher clarity refers to more distinct exhibition of the features. A GW tracking algorithm is used to identify the waves and to sort the albedo power.

In the Alpine region, the most dense subnetwork of identical NDMC (Network for the Detection of Mesospheric Change) instruments can be found. With these instruments the mesopause temperature is derived each night. The data can be used for the investigation of the amount of energy which is transported by small-scale atmospheric waves, known as gravity waves, provided that the so-called Brunt–Väisälä frequency is known. Information about the variability of this parameter is provided here.

Recently, theoretical and laboratory studies have suggested an additional
nighttime channel of transfer of vibrational energy of OH molecules to CO2 in the
mesosphere and lower thermosphere (MLT). We show that new mechanism brings
modelled 4.3 μm emissions very close to the SABER/TIMED measurements. This
renders new opportunities for the application of the CO2 4.3 μm observations in
the study of the energetics and dynamics of the nighttime MLT.

This study validates version 3.5 of the ACE-FTS NOy species data sets by comparing diurnally scaled ACE-FTS data to correlative data from 11 other satellite limb sounders. For all five species examined (NO, NO2, HNO3, N2O5, and ClONO2), there is good agreement between ACE-FTS and the other data sets in various regions of the atmosphere. In these validated regions, these NOy data products can be used for further investigation into the composition, dynamics, and climate of the stratosphere.

These global results can be directly compared with 3-D models and will help in understanding not only the physical processes but also how they affect the Earth's climate. The simultaneous measurements of ozone and temperature will give added insight into the dynamics and photochemistry of the middle and upper atmosphere.

HF, the dominant stratospheric fluorine reservoir, results from the atmospheric degradation of anthropogenic species such as CFCs, HCFCs, and HFCs. All are strong greenhouse gases, and CFCs and HCFCs deplete stratospheric ozone.
We report the comparison of HF global distributions and trends measured by the ACE-FTS and HALOE satellite instruments with the output of SLIMCAT, a chemical transport model. The global HF trends reveal a slowing down in the rate of increase of HF since the 1990s.

Sudden stratospheric warmings (SSWs) influence the atmospheric circulation over a large range of altitudes and latitudes. We investigate the global distribution of small-scale gravity waves (GWs) during SSWs as derived from 13 years of satellite observations.
We find that GWs may play an important role for triggering SSWs by preconditioning the polar vortex, as well as during long-lasting vortex recovery phases after SSWs. The GW distribution during SSWs displays strong day-to-day variability.

A more detailed understanding of satellite O3 profile data records is vital for further progress in O3 research. To this end, we made a comprehensive assessment of 14 limb/occultation profilers using ground-based reference data. The mutual consistency of satellite O3 in terms of bias, short-term variability and decadal stability is generally good over most of the stratosphere. However, we identified some exceptions that impact the quality of recently merged data sets and ozone trend assessments.

Energetic particles from the sun produce NOx (=N+NO+NO2) in the mesosphere/lower thermosphere. The NOx can be transported downward in the stratosphere during polar winter where NOx eventually depletes O3. This entire chain is the so-called energetic particle precipitation (EPP) indirect effect.
Here we show downward propagating negative stratospheric O3 anomalies during Antarctic polar winter. The O3 anomalies are caused by geomagnetic activity and show strong hints of the EPP indirect effect.

This paper deals with the retrieval of atomic oxygen concentration profiles in the Earth's upper mesosphere/lower thermosphere region from SCIAMACHY observations of oxygen green line airglow emissions. Atomic oxygen is one of the most important chemical constituents of this atmospheric region, and long-term satellite data sets are rare. The paper includes a detailed description of the retrieval algorithm, an error budget, validation results and some first scientific analyses.

Satellite data over the 11-year solar cycle from 2002 to 2014 show that the response of atmospheric temperatures are in phase with the sun's activity from 50 to 100 km. The ozone variations are also in phase with those of temperature between ~ 80 and 100 km but are mostly out of phase between ~ 50 and 80 km. This is consistent with the idea that dynamics are more in control from 80 to 100 km, while ozone photochemistry is more in control from ~ 50 to 80 km.
