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 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.
We are proud to announce that ACP has just published its first ACP Letter. ACP Letters are short research articles that report particularly important results and major advances in a concise and engaging style. Read more.
The journal metrics were updated and the current numbers are available from the metrics box on the left-hand side.
A new study shows that air pollutants from the smoke of fires from as far as Canada and the southeastern U.S. traveled hundreds of miles and several days to reach Connecticut and New York City, where it caused significant increases in pollution concentrations.
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.
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 journal metrics were updated and the current numbers are available from the metrics box on the left-hand side.
A video abstract is a short video statement providing authors with the opportunity to present background information about their findings and to showcase their research activities to a wider audience.
Copernicus Publications recently launched its full-text HTML workflow and optimized the ACP website for mobile devices. Thereby, the user experience is significantly enhanced when reading ACP articles.
To facilitate the publication procedure for authors from Helsinki University, Copernicus Publications and Helsinki University Library have signed an agreement on a central billing of article processing charges (APCs).
Data underpinning any research finding should be findable, accessible, interoperable, and reusable (FAIR) – not only for humans, but also for machines. Therefore, Copernicus Publications requests that such data are available upon publication of an article.
As of 1 May 2018 the centralized payment of article processing charges (APCs) with the Leibniz Association has been extended to 53 Leibniz Institutions participating in the Leibniz Association's Open Access Publishing Fund.
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.
After more than 16 years of serving the scientific community of Atmospheric Chemistry and Physics (ACP) with great dedication and success, William T. (Bill) Sturges has resigned from the executive committee that coordinates the ACP editorial board.
"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.
Authors from the Potsdam Institute for Climate Impact Research (PIK) will profit from a new institutional agreement with Copernicus Publications starting 23 August 2017. The agreement which is valid for the first author enables a direct settlement of article processing charges (APCs) between the PIK and the publisher.
The general obligations for editors, referees, and authors have been revised to give advice for the appropriate handling of literature suggestions.
To make it as easy as possible for users without technical knowledge to cut and paste or click to share DOIs, CrossRef has changed the display and citation guidelines for DOIs from "doi:10.5194/abcd" to "https://doi.org/10.5194/abcd".
Since early 2016, Copernicus Publications has been enabling authors to connect their articles with underlying or related material such as research data, model code, or scientific videos. To enhance reproducibility it is now also possible to include International Geo Sample Numbers (IGSNs) as assets.
In 2016, the 17 EGU–Copernicus peer-reviewed open-access journals experienced significant growth. We published over 3300 final-revised papers, corresponding to some 53,500 pages, a growth of about 10% compared to the previous year. These papers were downloaded over 645,000 times.
Recently we have become aware of a case of scientific malpractice by an editor of two of our journals (SOIL and SE) who used the position as editor and reviewer to disproportionately promote citations to personal papers and associated journals. Please read the published editorial.
Authors from the Technical University Darmstadt will profit from a new institutional agreement with Copernicus Publications starting 1 January 2017. The agreement which is valid for corresponding authors enables a direct settlement of article processing charges (APCs) between the university and the publisher.
Copernicus Publications and the Leibniz Association have agreed on a central billing of article processing charges (APCs) to facilitate the publication procedure for authors. So far three Leibniz institutes are participating in this agreement.
