In the coming days and weeks, readers of our journals will experience a facelift of our websites. Read more about the background.
We are sad to announce that the Atmospheric Chemistry and Physics community has lost a highly valued member: Prof Astrid Kiendler-Scharr passed away in February 2023. Please read our obituary.
The number of cloud droplets per unit volume is a significantly important property of clouds that controls their reflective properties. Computer models of the Earth's atmosphere and climate have low skill at predicting the reflective properties of Southern Ocean clouds. Here the authors investigate the properties of those clouds using satellite data and find that the cloud droplet number and cloud albedo in the Southern Ocean are related to the oceanic phytoplankton abundance near Antarctica.
After 20 years of pioneering its highly successful publication model with interactive discussion and open peer review in its discussion forum ACPD, ACP reached out to EGUsphere in 2022 allowing additional submission routes with preprint discussions outside of ACPD. As of today, discussions of ACP manuscripts will only take place on EGUsphere.
Copernicus Publications is delighted to announce a new agreement with the UK-based Jisc (Joint Information Systems Committee) to streamline open-access publishing for their members. Read more.
The origins of the abundant cloud condensation nuclei (CCN) in the upper troposphere (UT) of the Amazon remain unclear. With model developments of new secondary organic aerosol schemes and constrained by observation, the authors show that strong aerosol nucleation and condensation in the UT is triggered by biogenic organics, and organic condensation is key for UT CCN production.
New particle formation (NPF) is a source of atmospheric aerosol number concentration that can impact climate by growing to larger sizes and under proper conditions form cloud condensation nuclei (CCN).
Peering inside common atmospheric particles is providing important clues to their climate and health effects, according to a new study by University of British Columbia chemists. Read more.

Pollution particles cool climate and offset part of the global warming. However, they are washed out by rain and thus their effect responds quickly to changes in emissions. The authors show multiple datasets to demonstrate that aerosol emissions and their concentrations declined in many regions influenced by human emissions, as did the effects on clouds.
It was September 2001 when the first preprint was posted for public peer review and interactive public discussion in ACP. Time to celebrate!

This new policy will allow authors to retrospectively update previous publications with their current names, including conference abstracts, preprints, and peer-reviewed articles.
Offline analyses of the hygroscopicity and composition of atmospheric aerosols are complementary to online analyses in view of the applicability to broader sizes, specific compound groups, and investigations at remote sites. This offline study characterized the composition of water-soluble matter in aerosols and their humidity-dependent hygroscopicity on Okinawa, a receptor site of East Asian outflow.
To ensure that ACP continues to represent the growing global community of atmospheric scientists that it serves, we deliberately invited colleagues who bring expertise from a wide range of countries. Read more.
The authors have undertaken atmospheric iodine monoxide (IO) observations in the global marine boundary layer with a wide latitudinal coverage and sea surface temperature (SST) range. They conclude that atmospheric iodine is abundant over the Western Pacific warm pool, appearing as an iodine fountain, where ozone (O3) minima occur.
EGUsphere, the innovative open-access repository created by the European Geosciences Union and Copernicus Publications, is growing. For the first time, authors will be able to upload preprints to the online resource, taking advantage of EGU’s pioneering public peer-review process, whilst preparing their papers for future release.
At the end of the year, we would like to express our deep gratitude for our collaboration with all editors, referees, and authors in 2021. Please take a look at our Christmas card. Since our virtual office is closed from 23 Dec to 2 Jan and a significant number of editors and referees pause their work over the Christmas days, we extended all journal review deadlines: deadlines expiring shortly before or over Christmas have been extended to the week after and deadlines expiring after Christmas or over New Year have been extended to after New Year’s Day. Season's greetings and a happy New Year. Please stay healthy.
Ammonia (NH3) gas emitted from soils and biomass burning contributes to particulate air pollution. The authors used satellite observations of the atmosphere over Africa to show that declines in NH3 concentrations over South Sudan's Sudd wetland in 2008–2017 are related to variation in wetland extent.
Vertical profiles of black carbon (BC) in the Arctic were measured during the PAMARCMiP aircraft-based experiment in spring 2018 and compared with those observed during previous aircraft campaigns in 2008, 2010, and 2015.
Aerosol particle pH is well-buffered by alkaline compounds, notably NH3 and crustal elements. NH3 is found to supply remarkable buffering capacity on a global scale, from the polluted continents to the remote oceans.
In April 2021 the EGU Publications Committee launched the first author survey to routinely ask authors about their publishing experience in EGU journals, in order to learn more about how EGU and Copernicus can serve the scientific community with their publications. Over the last 6 months, 160 contact authors answered the survey representing about 10% of the papers published during this time. We are delighted about the positive feedback and thank all authors. Please read the full report.
Experiments at CLOUD show that in polluted environments new particle formation (NPF) is largely driven by the formation of sulfuric acid-base clusters, stabilized by amines, high ammonia concentrations or lower temperatures.
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 journal metrics were updated and the current numbers are available from the journal metrics overview.
The authors find that simulated stratospheric sulfate geoengineering could lead to warmer Eurasian winters alongside a drier Mediterranean and wetting to the north.
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.

The Spanish National Research Council (Consejo Superior de Investigaciones Científicas, CSIC) will now provide a publication fund for their corresponding authors publishing in Copernicus' open-access journals.
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.
While Cristina Facchini and Rolf Sander have resigned from the executive committee, we are very happy to welcome Barbara Ervens as a new ACP executive editor.
