We examined how major wintertime disruptions of the Arctic atmosphere affect the downward transport of nitric oxide. Using satellite observations and a whole-atmosphere model, we found that large-scale waves repeatedly organize nitric oxide into distinct regions and that this transport differs between split and displaced polar vortices. The results improve understanding of how atmospheric dynamics control chemical transport between the upper atmosphere and stratosphere.

We introduce two performance modeling tools, the Linear Performance Estimator (LPE) and the Fast L2 Simulator (FL2S), developed for CAIRT, a proposed ESA Earth Explorer mission. CAIRT aims to observe the middle atmosphere using an Imaging Fourier Transform Spectrometer. LPE quantifies spatial resolution and tomographic retrieval uncertainties, while FL2S generates synthetic data products that mimic the retrieval chain. Together, they demonstrate CAIRT's ability to meet scientific requirements.

In numerically simulating atmospheric phenomena that extend into the thermosphere, it is important to allow the atmosphere to expand/contract vertically in response the significant diabatic heating/cooling that occurs at these high altitudes. This paper examines the suitability of employing a new treatment of the upper boundary in the MPAS-A model that permits its vertical mobility in deep-atmosphere global applications.

Short summary
Vertical winds are a crucial atmospheric parameter in the mesosphere/lower thermosphere and are connected to adiabatic heating and cooling of the atmosphere. Mesospheric temperatures are affected by the vertical transport driven by a pole-to-pole circulation with upwelling in the summer hemisphere and downwelling in the winter hemisphere. We present results based on a new retrieval technique for the seasonal climatological vertical winds and an intercomparison to current state-of-the-art models.

This paper presents an ice hydrometeor retrieval algorithm for the PolSIR and PMM satellite missions. The algorithm combines Bayesian Monte Carlo Integration with the Optimal Estimation Method, extending retrieval capability beyond the limitations of the a priori database. Experiments using simulations and airborne observations show that the algorithm effectively reduces discrepancies between observations and simulations and improves the accuracy of retrieved ice cloud microphysical properties.

Incoherent scatter radars (ISRs) are an important measurement tool for space weather research. However, ISR measurements require previous knowledge of the state of the ionosphere, especially the ratio of atomic oxygen ions (O+) to electrons. We present ISR measurements during the May 2024 "Mothers' Day Storm" and apply data assimilation-based O+ ratios, which should result in more accurate ISR measurements. The advantages and disadvantages of our method are compared to those of other approaches.

We investigate how rising CO₂ changes the migrating diurnal tide driven by solar heating and latent heat. Using a state-of-the-art model under the most extreme scenario in the Intergovernmental Panel on Climate Change report, we find that the tide strengthens between 20–70 km but weakens between 90–110 km. The increase likely reflects lower density and stronger tropical convection, whereas the decrease is consistent with enhanced diffusion.

The E-region of the Earth’s ionosphere plays an important role in atmospheric energy balance and High Frequency radio propagation. In this paper, we compare predictions from two recently developed ionospheric models to observations by ionospheric sounders (ionosondes). Overall, the models show reasonable agreement with the observations. However, there are several areas for improvement in the models as well as questions about the accuracy of the automatically processed ionosonde dataset.

Nitric oxide in the upper atmosphere varies with solar activity. Observations show that this starts a chain of processes affecting the ozone layer and climate system. This is often underestimated in models. We compare five models which show large differences in simulated NO. Analysis of these discrepancies identify two processes which interact with each other: the balance between atomic and molecular oxygen in the thermosphere, and a poleward - downward transport in the winter thermosphere.

Concerns about climate change are growing due to its widespread impacts, including rising temperatures, extreme weather events, and disruptions to ecosystems. To address these challenges, urgent global action is needed to monitor the distribution of trace gases and understand their effects on the atmosphere.

Marine boundary layer (MABL) water vapor is among the key factors to couple the ocean and atmosphere, but it is also among the hardest to retrieve from a satellite remote sensing perspective. Here we propose a novel way to retrieve MABL specific humidity profiles using the GNSS (Global Navigation Satellite System) Level-1 signal-to-noise ratio. Using a machine learning approach, we successfully obtained a retrieval product that outperforms the ERA-5 reanalysis and operational Level-2 retrievals globally, except in the deep tropics.

We studied how the healing of the Antarctic ozone layer is affecting winds high above the South Pole. Using ground-based radar, satellite data, and computer models, we found that winds in the upper atmosphere have become stronger over the past two decades. These changes appear to be linked to shifts in the lower atmosphere caused by ozone recovery. Our results show that human efforts to repair the ozone layer are also influencing climate patterns far above Earth’s surface.

This study explores the potential of two newly launched commercial Global Navigation Satellite System (GNSS) radio occultation (RO) satellite missions for advancing Arctic lower-atmospheric studies. The products have a good sampling of the lower Arctic atmosphere and are useful to derive the planetary boundary layer (PBL) height during winter months. This research is a step towards closing the observation gap in polar regions due to the decomissioning of Constellation Observing System for Meteorology, Ionosphere, and Climate (COSMIC-1) GNSS RO mission and the lack of high-latitude coverage by its successor (COSMIC-2).

We study how well the F10.7 and F30 solar radio fluxes have represented solar energy input in the thermosphere in the last 60 years. We found that increased saturation of radio fluxes at recent solar minima leads to an overestimation of solar energy, which changes the relation between thermospheric parameters and F10.7, but this is not an issue for F30 because of a relative increase in F30 with respect to F10.7. This explains why F30 has been found to represent solar energy better than F10.7.

Global Navigation Satellite System radio occultation data help monitor climate and weather prediction but are affected by residual ionospheric errors (RIEs). A new excess-phase-gradient method detects and corrects RIEs, showing both positive and negative values, varying by latitude, time, and solar activity. Tests show that RIE impacts polar stratosphere temperatures in models, with differences up to 3–4 K. This highlights the need for RIE correction to improve the accuracy of data assimilation.

The 2022 Hunga Tonga–Hunga Ha’apai (HTHH) volcanic eruption not only triggered broad-spectrum atmospheric waves but also generated unusual tsunamis which can generate atmospheric gravity waves (AGWs). Multiple strong atmospheric waves were observed in the far-field area of the 2022 HTHH volcano eruption in the upper atmosphere by a ground-based airglow imager network. AGWs caused by tsunamis can propagate to the mesopause region; there is a good match between atmospheric waves and tsunamis.

We estimate plume heights for the April 2021 La Soufrière daytime eruptions using GOES-17 near-limb side views and GOES-16–MODIS stereo views. These geometric heights are then compared with brightness-temperature-based radiometric height estimates to characterize the biases of the latter. We also show that the side view method can be applied to infrared imagery and thus nighttime eruptions, albeit with larger uncertainty.

We use ground-based airglow network observations, reanalysis data, and satellite observations to explore the propagation process of concentric gravity waves (CGWs) excited by a typhoon between the troposphere, stratosphere, mesosphere, and thermosphere. We find that CGWs in the mesosphere are generated directly by the typhoon but the CGW observed in the thermosphere may be excited by CGW dissipation in the mesosphere, rather than directly excited by a typhoon and propagated to the thermosphere.

Launched from the International Space Station, the IceCube radiometer orbited the Earth for 15 months and collected the first spaceborne radiance measurements at 874–883 GHz. This channel is uniquely important to fill in the sensitivity gap between operational visible–infrared and microwave remote sensing for atmospheric cloud ice and snow. This paper delivers the IceCube Level 1 radiance data processing algorithm and provides a data quality evaluation and discussion on its scientific merit.

Metal layers occur in the MLT region (80–120 km) from the ablation of cosmic dust. The latest lidar observations show these metals can reach a height approaching 200 km, which is challenging to explain. We have developed the first global simulation incorporating the full life cycle of metal atoms and ions. The model results compare well with lidar and satellite observations of the seasonal and diurnal variation of the metals and demonstrate the importance of ion mass and ion-neutral coupling.

Short summary
Upper mesospheric carbon monoxide's (CO) photochemical lifetime is longer than dynamical timescales. This work uses satellite observations and model simulations to establish that the migrating diurnal tide and its seasonal and interannual variabilities drive CO primarily through vertical advection. Vertical advection is a transport process that is currently difficult to observe. This work thus shows that we can use CO as a tracer for vertical advection across seasonal and interannual timescales.
