COVID-19 lockdown measures in spring 2020 led to cleaner air in central Europe. Densely populated areas benefitted mainly from largely reduced NO2 concentrations, while rural areas experienced lower reductions in NO2 but also lower ozone concentrations. Very low particulate matter (PM) concentrations in parts of Europe were not an effect of lockdown measures. Model simulations show that modified weather conditions are more significant for ozone and PM than severe traffic emission reductions.

Earth system models have a few persistent biases that impinge on our ability to make robust future regional predictions of precipitation. For the last fifteen years, there has been little to no improvement in these biases. This work presents an accurate representation of how dust absorbs radiation based upon its observed mineralogical composition and size distribution.

Secondary organic aerosol (SOA) is an important aspect of poor air quality for urban regions around the world, where a large fraction of the population lives. However, there is still large uncertainty in predicting SOA in urban regions.

The authors find satellite observations of atmospheric composition generally reproduce variability in surface air pollution, so they use their long record to estimate air quality trends in major UK and Indian cities.

Cloud responses to aerosol are time-sensitive, but this development is rarely observed. This study uses isolated aerosol perturbations from ships to measure this development and shows that macrophysical (width, cloud fraction, detectability) and microphysical (droplet number) properties of ship tracks vary strongly with time since emission, background cloud and meteorological state.

A long-standing mystery of metal ions within Es layers in the Earth's upper atmosphere is the marked seasonal dependence, with a summer maximum and a winter minimum. We report a large-scale winter-to-summer transport of metal ions from 6-year multi-satellite observations and worldwide ground-based stations. A global atmospheric circulation is responsible for the phenomenon. Our results emphasise the effect of this atmospheric circulation on the transport of composition in the upper atmosphere.

With great sadness, we have to announce that Paul J. Crutzen has passed away on 28 January 2021. Paul was not only an outstanding scientist and scholar, but a friend, colleague, and mentor for generations of atmospheric scientists. He had also been a long-time supporter of open-access publishing within EGU, where he played a key role in the foundation and establishment of its first OA journal, Atmospheric Chemistry and Physics, and served on its advisory board for many years. He will be sorely missed. Our thoughts are with his family. (Image credit: MPI for Chemistry)

Forest fires are an important source of reactive organic gases and aerosols to the atmosphere. The authors analyzed organic aerosols collected from an aircraft above a boreal forest fire and reported an increasing contribution from compounds containing oxygen, nitrogen, and sulfur as the plume aged, with sulfide and ring-bound nitrogen functionality.

Methane is an important energy source in Europe, but also a strong greenhouse gas. Previous research in the United States has shown that new equipment detects considerably more gas leaks than equipment currently used by local gas utilities. This also appears to be the case in two European cities, Hamburg in Germany and Utrecht in the Netherlands, researchers write today in Atmospheric Chemistry and Physics.

Concentrations of methane, a greenhouse gas about 28 times more potent than carbon dioxide, have risen steadily in Earth's atmosphere since 2007. Although several potential explanations, including an increase in methane emissions from the tropics, could account for this upsurge, due to a lack of regional data scientists have been unable to pinpoint the source. Now a study published in ACP uses satellite data to determine that one-third of the global increase originates in Africa's tropics.

In the right conditions, airplane contrails can linger in the sky as contrail cirrus – ice clouds that can trap heat inside the Earth's atmosphere. A new study published in ACP has found that, due to air traffic activity, the climate impact of contrail cirrus will be even more significant in the future, tripling by 2050.

The ozone layer – which protects us from harmful ultraviolet radiation – is recovering at the poles, but unexpected decreases in part of the atmosphere may be preventing recovery at lower latitudes, new research has found. The new result, published today in ACP, finds that the bottom part of the ozone layer at more populated latitudes is not recovering.

"Ozone depletion is a well-known phenomenon and, thanks to the success of the Montreal Protocol, is widely perceived as a problem solved," says University of East Anglia's David Oram. But an international team of researchers, led by Oram, has now found an unexpected, growing danger to the ozone layer from substances not regulated by the treaty.
