Short summary
Short summary
This paper presents recent advances in ICON-ART, a modeling system that simulates atmospheric composition—such as gases and particles—and their interactions with weather and climate. By integrating updated chemistry, emissions, and aerosol processes, ICON-ART enables detailed, scale-spanning simulations. It supports both scientific research and operational forecasts, contributing to improved air quality and climate predictions.

This study presents three simulations of atmospheric chemistry with the BASCOE model, driven by different meteorological data sets. These simulations include newly implemented SF6 chemistry, useful for stratospheric transport studies. Results compare well with satellite observations. The lifetime of six trace gases is computed and agrees with the literature, but SF6 shows larger sensitivity to the choice of meteorology. The lifetime of SF6 ranges from 1900 to 2600 years.

Our study aims to present a new method for incorporating top-down solar forcing into stratospheric ozone relying on linearized ozone scheme. The addition of geomagnetic forcing led to significant ozone losses in the polar upper stratosphere of both hemispheres due to the catalytic cycles involving NOy. In addition to the particle precipitation effect, accounting for solar UV variability in the ICON-ART model leads to the changes in ozone in the tropical stratosphere.

Short summary
Formation of nitric oxide NO in the upper atmosphere varies with solar activity. Observations show that it starts a chain of processes in the entire atmosphere 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 results point out problems related to the oxygen balance, and to the impact of atmospheric waves on dynamics. Both must be modeled well to reproduce the downward coupling.

Reduced ozone levels resulting from ozone depletion mean more exposure to UV radiation, which has various effects on human health. We analysed solar events to see what influence it has on the chemistry of Earth's atmosphere and how this atmospheric chemistry change can affect the ozone. To do this, we used an atmospheric model considering only chemistry and compared it with satellite data. The focus was mainly on the contribution of chlorine, and we found about 10 %–20 % ozone loss due to that.

Short summary
SF6-derived trends of stratospheric AoA from observations and model simulations disagree in sign. SF6 experiences chemical degradation, which we explicitly integrate in a global climate model. In our simulations, the AoA trend changes sign when SF6 sinks are considered; thus, the process has the potential to reconcile simulated with observed AoA trends. We show that the positive AoA trend is due to the SF6 sinks themselves and provide a first approach for a correction to account for SF6 loss.

Short summary
We investigate the subauroral flux maximum (at 60° North/South geomagetic) observed in low-energy particle channels. Two independent atmospheric impact measurements refute the subauroral flux under low Kp, pointing to instrumental crosstalk, likely from energetic electrons. We propose correction methods to mitigate contamination, ensuring accurate ionization estimates. Without correction, subauroral flux overestimates thermospheric ionization, underscoring the need for data refinement.

We investigated a subauroral particle flux maximum (located at 60 N/S with focus at 0–100 E) seen in the NOAA POES detector, which we attributed to crosstalk contamination of radiation belt electrons. Affected are the processed TED proton channels (which should already be corrected by NOAA) and lower MEPED channels. The particle flux in the contaminated area can be more than factor 2 higher than typical auroral flux. The region of intense particle crosstalk may be removed by a latitudinal cut.

Satellite measurements of stratospheric trace gases are essential for monitoring distributions and trends of these species on a global scale. Here, we compare the final MIPAS ESA Level 2 version 8 data (temperature and trace gases) with measurements obtained with the balloon version of MIPAS in terms of data agreement of both sensors, including combined errors. For most gases, we find a 5 % to 20 % agreement of the retrieved vertical profiles of both MIPAS instruments in the lower stratosphere.

From balloon measurements, we detected unprecedented, extremely powerful, electron precipitation over the middle latitudes. The robustness of this event is confirmed by satellite observations of electron fluxes and chemical composition, as well as by ground-based observations of the radio signal propagation. The applied chemistry–climate model shows the almost complete destruction of ozone in the mesosphere over the region where high-energy electrons were observed.

A new full 3-D time-dependent model, based on SOCOL-AERv2, of beryllium atmospheric production, transport, and deposition has been developed and validated using directly measured data. The model is recommended to be used in studies related to, e.g., atmospheric dynamical patterns, extreme solar particle storms, long-term solar activity reconstruction from cosmogenic proxy data, and solar–terrestrial relations.

Short summary
Recent analyses of isotopic records of ice cores and sediments have shown that very strong explosions may occur on the Sun, perhaps about one such explosion every 1000 years. Such explosions pose a real threat to humankind. It is therefore of great interest to study the impact of such explosions on Earth. We analyzed how the explosions would affect the chemistry of the middle atmosphere and show that the related ozone loss is not dramatic and that the atmosphere will recover within 1 year.
